This study examines the effects of both corporate reputation and negative emotions after failure (annoyance and irritation) on two voice-complaint behaviors, namely, direct firm and third-party complaints. Survey data were collected from 366 customers who experienced a banking service failure and complained. The research model was tested with Partial Least Square SEM using SmartPLS. The results showed that perceived corporate reputation has a greater impact than negative emotions on direct firm complaints, whereas negative emotions lead bank customers to 3rd parties. The relationship between corporate reputation and 3rd party complaints was fully mediated by the intensity of negative emotions. The study offers broader thinking on customer complaint behavior experience choices by proposing the notion that underlying antecedents of customers' different voice complaint behaviors may come from different sources, such as a bank's reputation appears to be judged by customers' experience or the intensity of the negative emotion after a failure. This study also contributes to the existing literature by examining the joint effects of firm reputation and negative emotions on complaint behavior in emerging markets.
