Companies can offer products and services as long as they satisfy their customers. One of the most significant factors affecting customer satisfaction is to resolve customer complaints. In this study, the survey data was collected related to the customer complaints process evaluation system of Turkish companies and answers were sought for questions such as how many complaints companies received on an industry basis and how long they resolved the complaints. The data was analyzed statistically, and the tests of the hypotheses were carried out. Chi-Square test, Mann Whitney U Test, sign test and correlation analysis were applied for testing hypotheses. According to the results, it is not enough just to start evaluating the customer complaint quickly, it is also very important to get a quick and accurate resolution to the complaint for customer satisfaction. Additionally, it has been found that personnel working in the complaint system should be trained continuously and customers should be involved in the complaint handling processes.
