The focus of the study is to examine the complaining behavior of young retail customers in Matara District, Sri Lanka. Survey method was used as the main research method and a structured questionnaire was used to gather data from 80 customers. Survey results revealed that customers make complaints mainly to obtain the restitution.

They dislike to complain to a third party or to take legal actions against the retailer. Further, it is notable that that young retail customers view complaining as wastage of their time and effort. The study further highlights that the young retail customers are not “self blamers”.
