The present study was a correlational-applied study. The population of this study was all customers who had more than two years of collaboration with the EN Bank and were living in Tehran. Therefore, those branches located in diverse districts of Tehran were selected from all branches across the country. Since each branch was associated with one of quadripartite districts, five branches were selected randomly from each district. Multi-phase cluster random sampling was carried out in these districts. To obtain a sample size, formula of ratio estimation with a relative error of 0.05 and a maximum variance value of 0.50 were used so that the total size of sample was determined as 400 approximately. This study utilized the descriptive survey method. For this purpose, researcher-made questionnaires were used. In order to determine the reliability of the above-mentioned questionnaires, Cronbach & apos; s alpha coefficient was used and it was determined as 0.813, which confirmed the questionnaires. In addition, the validity of these questionnaires was reviewed and confirmed using expert opinions and viewpoints of professionals working in the banking sector as well as respectful professors.
