Introduction Information Technology has changed at various levels and at a very fast pace, where it has an immediate impact on all businesses doing the actual service or product sales. This not only affects business owners but also customers who want to keep up with the latest technological advancements, which puts pressure on service providers because they also have to live up to their customers' expectations to avoid losing a single customer. When a customer does not get the service he or she wants, it can lead to him or her quitting and contacting another service provider. Providing better service compared to the services provided by your competitors increases your business’s chances of retaining your customers, attracting new customers, and create customer satisfaction with the service you provide. To improve the quality of service provided by business establishments, banks are especially important to ensure that customers of a particular bank get the best and most convenient service to trust those customers. The ability to provide high service quality will strengthen the image, enhance the retention of customers, attracting new potential customers through customer satisfaction and loyalty (Rahman, 2013). Good service delivery is a key pillar of every business to be sure and plan for the future because it gives the impression that customers are connecting to the service provided by their needs. When the quality of the service outweighs the customer's expectations, there is more excitement than the customer expects and it can be reflected in the customer's emotions including word of mouth, re- requesting services, or encouraging others to go to the bank or company that has received the best service. When the quality of service is equal to the needs of the customer, there is a sense of satisfaction with the service received. Both of these are good for any business that wants to continue to thrive in providing better services. The worst thing to be considered by banks to take care and maintain customers is to ensure that the quality of the service is not less than the customer’s expectations as it creates customer dissatisfaction with the service and this could lead to the loss of a single customer. To understand customer needs is become an important factor for the banking industry and most of the customers now more prefer to opt for technology-based service delivery (Khan, Mir, Khan, Raza, & Khan, 2016). Since the services and products provided by the banks are the same or have very small differences that cannot be seen by everyone, there is a strong rivalry between the banks in terms of customer acquisition and retention. One of the researchers who researched Jamuna Bank Limited in Bangladesh revealed that banking industry in Bangladesh today has become a very dynamic, competitive and complex environment where financial products and services offered by the commercial banks have only minor differences, where the industry situation is having a tremendous increase in customer demand and this require greater transformation with an intense focus on customer satisfaction and loyalty (Rahman, 2013). In search of customer solutions and providing the high quality of services and continuing to strive to be the first provider of market needs, banks have opted to start providing services to their customers with technologies. Mahmoud Kamal Abouraia, Hamed J. H. Usrof, (2015) stated that banks describe their activities and products through electronic banking to improve their competitive position and image. The adoption of digital innovation has provided tremendous benefits to the customers and it supported service quality such as access, convenience, speed, and economy. The researcher added that electronic banking services can reduce 161 administrative costs, operational costs, and increase customer satisfaction. According to Khan et al., (2016) electronic banking includes phone or mobile banking, Internet or online banking and email banking and Mahmoud Kamal Abouraia, Hamed J. H. Usrof, (2015) cited Auta (2010) who revealed that electronic banking can also be defined as a variety of platforms include: (i) internet banking (or online banking), (ii) telephone banking, (iii) TV-based banking, (iv) mobile phone banking, and e-banking (or offline banking). 2. Literature Review Dutch-Bangla Bank Limited (DBBL) started operation on 3rd June 1996 as Bangladesh's first joint venture bank in the private sector. The bank was an effort by local shareholders spearheaded by M Sahabuddin Ahmed (founder chairman) and the Dutch company FMO (Banglapedia.com). The bank is listed with the Dhaka Stock Exchange Limited and Chittagong Stock Exchange Limited (Wikipedia.com). Dutch-Bangla Bank is Bangladesh's most innovative and technologically advanced bank. Dutch-Bangla Bank Ltd stands to give the most innovative and affordable banking products to Bangladesh. Amongst banks, Dutch-Bangla Bank is the largest donor in to social causes in Bangladesh (www.dutchbanglabank.com). The following table shows the mission, vision, and core objectives of Dutch-Bangla Bank Limited. Statements Mission Dutch-Bangla Bank engineers’ enterprise and creativity in business and industry with a commitment to social responsibility. "Profits alone" do not hold a central focus in the Bank's operation; because "man does not live by bread and butter alone". Vision Dutch-Bangla Bank dreams of better Bangladesh, where arts and letters, sports and athletics, music and entertainment, science and education, health and hygiene, clean and pollution-free environment, and above all a society based on morality and ethics make all our lives worth living. Dutch-Bangla Bank’s essence and ethos rest on a cosmos of creativity and the marvel-magic of a charmed life that abounds with the spirit of life and adventures that contributes towards human Development. Core Objectives Dutch-Bangla Bank believes in its uncompromising commitment to fulfill its customer needs and satisfaction and to become their first choice in banking. Taking a cue from its pool esteemed clientele, Dutch-Bangla Bank intends to pave the way for a new era in banking that upholds and epitomizes its vaunted marquees "Your Trusted Partner" The DBBL annual report of 2017 noted that in today’s global business scenario, particularly in the banking sector, technology plays a vital role in executing all sorts of customer- friendly banking operations with cost-effective services and due to the intense competition and the ever- increasing growth in this banking sector, to overcome it is to focus on technology due to technology has become an aide of necessity rather than an option in financial institutions just to satisfy the growing service demand of the customer cost- effectively. Automated Teller Machine (ATMs) was one of the first electronic banking systems used by the bank to provide some of the key banking services that were introduced between the 1950s and 1960s but were first used in 1972 by the City National Bank of Cleveland. ATMs are computerized telecommunications devices used by banks to provide customer service without encountering a bank employee. The DBBL started its ATM/POS service back in 2004 and become the leader soon. DBBL is continuing its mission to increase the number of ATMs in the country as their website currently shows that the bank has 4763 ATMs while by the end of 2018 it had about 4705, according to the 2018 DBBL annual Report, (2018). Internet banking is a way for a bank customer to withdraw money, view the balance on an account, and make a transfer to another account via the internet using a telephone, computer, or other devices that can use the internet. What online banking offers are an opportunity to perform different bank operations, where a customer can access his or her bank account via the Internet (Khan et al., 2016). This allows a customer to access his/her account from home or office by internet connectivity. DBBL has been one of the pioneers in introducing Internet Banking in the country back in 2004 and this service is offered free of charges. Mobile banking is another electronic banking method adopted by banks from all over the world to facilitate its customers in transaction needs. Due to the increasing number of mobile phone users in the world and Bangladesh in general. This allows banks to use telephones to provide banking services including withdrawals, balance checks, and payment of some of the key services. Ongori, (2013) asserted that the increased use of mobile banking may be attributed to the increased use of mobile phones in the country. Mobile banking is also prevalent due to the convenience of the usage of mobile devices. According to Khan et al., (2016), the information technology (IT) is available today for customer acquisition by creating automation in banking process by providing and delivering ease and efficiency to the bank’s customers. In the banking sector, automation of banking services is done by making it easier for the customer to get the services he or she wants through electronic means. Mahmoud Kamal Abouraia, Hamed J. H. Usrof, (2015) postulated that adoption of digital innovation has provided tremendous benefits to customers and it supports service quality such as access, convenience, speed, and economy. In a study conducted by Khan et al., (2016) recalled that e- banking is using as a delivery model for the delivery of services like withdrawal, electronic bill payment, recharges and online transfer and added that electronic banking includes phone or mobile banking, Internet or online banking and e- mail banking and ATM. In the 2018 Annual Report of Dutch- Bangla Bank Limited, DBBL was the first bank in Bangladesh to be fully automated and introduce electronic banking. DBBL provides online banking through its branches and several agents, ATM/Fast Track, Mobile banking „Rocket‟, Internet banking, SMS banking, Debit card, Credit card, Virtual card, E-payment, and so on. 162 3.

Data Collection and Materials This study is an empirical study mainly based on primary data from a survey. Based on this goal, the structured questionnaire is organized to collect information from customers. The questionnaire to be used in this study consists of questions based on demographic characteristics of the customer who will participate in this study and the statements to assess the extent to which Dutch Bangla Bank’s customers satisfied with the self-service technology services they have chosen to use include: ATM banking, Internet banking and or Mobile banking. Those statements will be measured and investigated using a five-point scale. The scale consists of 36 statements; each statement has about five choices that the researcher chooses based on the extent to which he or she strongly disagrees or strongly agrees with each statement. The points of a used five-point scale refer to Strongly Agree (5), Agree (4), Neutral (3), Disagree (2), and Strongly Disagree (1). The final questionnaire was put into operation after correction and rephrasing statements to be used. Information will be collected by sending a questionnaire link to the participants of this study via e-mail, WhatsApp, and any other means that will make it easier for us to share questionnaire online because it is very difficult to find people nowadays due to coronavirus prevention guidelines in the country. The researcher will only use data collected using the questionnaire as it is not intended to access customers‟ data from Bank. 6. Data Analysis and Results 6.1. Reliability Analysis The researcher can get rid of irrelevant variables with this 163 method. Cronbach's Alpha was used to evaluate the nine variables' internal reliability. They were accepted because, as Lassar (2000) suggested, they met the general lower limit for Cronbach's Alpha of 0.70.

Dependent Variable: Customer Loyalty 7. Conclusion and Discussion An essential requirement for an enterprise is customer satisfaction. The customer fee is beneficial to the company. However, in the competitive market of today, a great carrier is essential. The purpose of this study was to determine customer satisfaction with service quality in relation to service quality dimensions. Based on the findings, the search objectives were achieved by determining the factors of service quality such as reliability, accessibility, responsiveness, empathy, and tangibles. By examining the influence of service quality on customer satisfaction among private Bangladeshi banks, it was discovered that, out of the five service quality dimensions, Tangible has the highest Mean score, and responsiveness has the lowest mean score. Additionally, the study demonstrated that tangibility, 166 dependability, responsiveness, assurance, and empathy have a significant impact on customer satisfaction. As a result, customer satisfaction is greatly impacted by provider-friendly practices. The personal area banks' success and survival depend on these two factors working together. It was discovered that excellent customer service is essential to blissful customer satisfaction. Banking sector requirements are now more diverse and distinctive than ever before in the global economy. Therefore, banks must prioritize service quality to satisfy customers in every aspect of service quality. References [1] Abasimi, I., Evans, A. A., & Martin, A. Y. A. (2018).
