With the advent of deregulation, globalization, and increased competitive pressure, the banking sector began to recognize that the "customer" is the brand ambassador and that retaining customers is less expensive than acquiring new customers for the services. Loyal customers remain longer and refer different customers to banks. A term relationship with customers helps the bank understand customer needs. It is an opportunity to introduce customized products on service and strategically pitch their products to customers. Customers comprehend the banking procedures, which reduces the working expenses arising out of customer related errors. Since the expense of securing a new customer is relatively high when compared to retaining an existing customer, banks started using customer relationship management as a tool to maintain great and consistently enduring relationships with customers. The data are collected through a questionnaire, and the sampling technique is stratified random sampling technique.
