Consumer complaints can be made for many reasons, mostly from negative episodes of consumption. However, there is a group of individuals who make complaints to companies without necessarily being unsatisfied. This conduct is called a fraudulent claim, which occurs when the purpose of the consumer in making the claim is for some monetary or social profit at the expense of the company. Despite the relevance of the theme, there are few studies about it in the area of marketing, mainly in Brazil. Although there are authors who investigate the subject, it is difficult to affirm what motivates individuals to follow this line of behavior. Ahead of this framework, the present study aimed to analyze the relationship between fraudulent claims and Brazilian culture, based on the motivations that lead to support this type of behavior. For this, a qualitative research was carried out, using data interviews in depth with 27 consumers, guided using the projective technique. The analysis of the data indicates different reactions of respondents to fraudulent complaints, diverging between acceptance and rejection of opportunistic behavior. It was possible to perceive that there is a close relationship between Brazilian culture and fraudulent claims, which revolve around the idea of Brazilian way, trickery, cleverness, and bad faith, as well as the link between religion and behaviors considered as wrong.
