Hence, banks focus on service quality as a core competitive strategy. Service quality offers a way of achieving success among competing services, particularly in banks, where establishing service quality may be the only way of differentiating oneself. Excellent customer service can improve the bank's ability to lure affluent prospects, elevate the bank's profitability, lower bank operation costs, and/or creates greater customer loyalty.

Therefore, the sample size consists of 640 customers. To study the perception of the customers, chi-square test, analysis of variance, student t test, paired comparison t-test, analysis of co-efficient of variation, discriminant function analysis, multiple discriminant function analysis, multiple regression analysis and percentage analysis have been employed.
