The establishment of high-quality customer service in the banking industry plays a crucial role in fostering customer satisfaction and loyalty (Karim & Chowdhury, 2019). In light of intensifying competition within the financial sector, banks are acknowledging the importance of delivering exceptional customer experiences as a means of both retaining current customers and attracting new ones (Omar, Rahman, & Zainuddin, 2019). The evaluation of customer service quality involves various elements that collectively impact a customer's perception of the service provided by the bank. The provision of responsive service is a fundamental aspect of ensuring high-quality customer service. According to Saravanakumar and SuganthaLakshmi (2012), it is anticipated by customers that their inquiries and concerns will be addressed promptly and efficiently. The failure to promptly respond to customer inquiries can result in customer dissatisfaction and a perception of the bank's lack of dedication to fulfilling their requirements (Clemes, Gan, & Kao, 2016). In contrast, financial institutions that place a high value on promptly addressing customer needs and offering timely resolutions are able to cultivate trust and nurture favourable customer connections (Ismail, Omar, & Haron, 2017). Efficiency is an essential component of customer service quality within the banking industry. According to Tan, Ramayah, and Abdul-Majid (2017), customers have a preference for expeditious and streamlined transactions. According to Sureshchandar, Rajendran, and Anantharaman (2002), extended waiting periods, intricate procedures, and system failures have the potential to result in customer dissatisfaction and attrition. According to Liao and Wang (2009), the optimization of operational processes and the utilization of technological advancements can significantly improve the efficiency of banks. This, in turn, enables customers to carry out transactions with ease and convenience. The inclusion of personalization is a significant factor in enhancing the quality of customer service. According to Qureshi, Khan, and Hijazi (2019), customers demonstrate a positive reception towards personalized services that are specifically designed to meet their individual preferences and financial requirements. Banks have the ability to provide personalized recommendations and products to customers by comprehending their individual customer profiles and financial objectives. This practice fosters a sense of belonging and loyalty among customers (Prabhakar, 2018). In addition, the successful resolution of complaints plays a crucial role in ensuring the overall quality of customer service. According to Ranaweera and Prabhu (2003), it is anticipated by customers that their complaints will be treated with seriousness and addressed promptly. According to Patterson (2003), financial institutions that demonstrate empathy and efficiency in addressing customer complaints have the potential to transform dissatisfied individuals into devoted advocates. In order to consistently enhance the quality of customer service, banks frequently utilize customer feedback mechanisms, such as surveys and feedback portals (Nguyen & LeBlanc, 2001). According to Manaf, Rosbi, and Bahari (2013), these tools facilitate the acquisition of customer insights and the identification of areas for improvement by banks. Banks exhibit their dedication to improving the customer experience by actively soliciting and implementing customer feedback (Ndubisi, 2007). The correlation between the quality of customer service and customer satisfaction is a primary area of interest within the field of service marketing and management. The intricate relationship between customers' perceptions and expectations has been the subject of study in various theoretical frameworks, including the SERVQUAL model and the Kano model. These frameworks aim to provide insights into understanding this relationship. The SERVQUAL model, which was first proposed by Parasuraman, Zeithaml, and Berry in 1985, is a highly prevalent framework utilized for evaluating the quality of customer service (Parasuraman, Zeithaml, & Berry, 1985). The present model places significant emphasis on five fundamental dimensions of service quality, namely reliability, responsiveness, assurance, empathy, and tangibles. Reliability pertains to the service provider's capacity to consistently and accurately deliver the promised service. Responsiveness refers to the inclination to assist customers in a timely and effective manner. Assurance pertains to the level of knowledge and courtesy exhibited by employees, as well as their capacity to inspire trust and instill confidence in customers (Hasan & Chowdhury, 2023). The concept of empathy pertains to the extent of concern and personalized consideration provided to customers. Tangibles refer to the material elements within the service environment that have an impact on customer perceptions. The SERVQUAL model is utilized to evaluate the disparity between customer expectations and the perceived delivery of services, thereby allowing organizations to pinpoint areas for enhancement in order to augment customer satisfaction. In contrast, the Kano model, formulated by Professor Noriaki Kano, centers its attention on comprehending the manner in which diverse service attributes influence customer satisfaction (Kano, Seraku, Takahashi, & Tsuji, 1984). The Kano model classifies service attributes into five distinct categories, namely basic, performance, excitement, indifferent, and reverse. Fundamental attributes are indispensable components that, when fulfilled, do not inherently guarantee heightened satisfaction but can engender dissatisfaction if left unmet. There exists a direct relationship between performance attributes and customer satisfaction, whereby increased levels of performance result in elevated levels of satisfaction (Hasan, Shafin, et al., 2023). Excitement attributes refer to unanticipated characteristics that, upon being presented, generate favorable surprises and augment customer contentment. The presence or absence of indifferent attributes has minimal influence on customer satisfaction. Reverse attributes refer to specific characteristics or features that, when they exist, result in a negative customer experience or dissatisfaction. Through a comprehensive understanding of various attribute categories, organizations can strategically allocate resources to effectively surpass customer expectations. Both the SERVQUAL and Kano models emphasize the significance of meeting and exceeding customer expectations in order to attain elevated levels of customer satisfaction (Hasan & Karim, 2023). The SERVQUAL model primarily aims to identify discrepancies between customers' expectations and their perceptions of the service they receive. On the other hand, the Kano model places emphasis on the diverse effects that different service attributes have on levels of satisfaction. A multitude of scholarly investigations have examined the correlation between the quality of customer service and customer satisfaction within the banking industry. These studies have provided valuable insights into the pivotal factors that impact customers' perceptions and their subsequent loyalty. These studies have provided significant contributions in assisting banks in developing effective strategies to improve customer experiences and attain higher levels of customer satisfaction. Effective communication plays a pivotal role in determining the quality of customer service within the banking industry. Multiple studies have demonstrated that the level of customer satisfaction is significantly impacted by the quality of communication between bank representatives and customers (Haque, 2019; Lee & Hsieh, 2019). Effective and concise dissemination of information pertaining to banking products, services, and policies has the potential to foster a favorable perception among customers, thereby resulting in heightened levels of satisfaction and loyalty (Rashid, Hassan, & Rahman, 2021). The examination of responsiveness is a crucial element within the realm of customer service quality and satisfaction in the banking industry. Numerous studies have provided evidence indicating that customers place significant importance on prompt and effective responses to their inquiries and grievances (Nasir & Hanudin, 2017; Mohamed & Rashid, 2016). According to Thaichon and Quach (2017), financial institutions that place a high emphasis on being responsive and promptly resolving customer concerns are more inclined to cultivate favourable customer experiences and establish enduring relationships. Trust is an essential element that consistently arises in prior research (Hasan, Siam, et al., 2023). The significance of trustworthiness in the banking sector cannot be overstated, as customers attach great value to their trust in the bank's integrity and dependability (Alalwan et al., 2020). According to Hu, Zhang, Zhao, and Yuan (2019), the establishment of trust between customers and banks plays a crucial role in enhancing customer satisfaction and loyalty. This trust can be cultivated through the provision of consistent service quality and adherence to ethical conduct. Furthermore, scholarly research has examined the effects of service recovery on customer satisfaction in instances of service failures (Liu & Jang, 2009). The efficacy of banks in effectively addressing customer complaints and recuperating from service failures has the potential to augment customer satisfaction, thereby potentially fostering heightened levels of loyalty in comparison to customers who have not experienced any issues (Mittal, Kumar, & Tsiros, 1999). The investigation of the role of technology in service quality and customer satisfaction has also been a topic of scholarly inquiry (Emon, 2023). Numerous scholarly investigations have been conducted to explore the impact of digital banking channels on customer experiences (Narteh, Agbemabiese, & Amponsah, 2021). The adoption of technological advancements, such as mobile banking applications and online platforms, can provide enhanced convenience and accessibility, thereby leading to increased levels of customer satisfaction (Emon et al., 2023).
