Data on retail customers’ satisfaction with banks in Greece

The aim of this database is to present data on customers’ satisfaction with the 4 major banks operating in Greece. The data were collected in four consecutive semesters, between June 2017 and June 2019. Initially 1,255 questionnaires were responded at the first semester. Those who agreed to participate in the survey and returned the questionnaire, consented that the same questionnaire would be delivered to them for another three semesters. In this way, 5,018 valid questionnaires were finally collected. To obtain the needed data a 5point Likert scale questionnaire was electronically distributed using random sampling. In the questionnaire’s scale, 0 denotes totally dissatisfied, while 4 denotes totally satisfied.
