This study aimed to identify and compare the different strategies used by males and females in making complaints. Both genders adopt different strategies when making complaints.  In this qualitative study, the content analysis method was adopted, and based on Trosborg's Theory of Complaint, complaints messages posted by 23 Twitter users were analyzed. The results showed that males perform dissatisfaction more frequently than females. However, females use blame strategy at a higher frequency than males. This research revealed a new perspective on gender differences and valuable insights influencing complaint-making strategies.
