I am writing to formally lodge a complaint about the unacceptable behavior of one of your customer service representatives. I received a call from a Trip.com phone number, during which the representative, a female manager, was extremely rude and unprofessional. Throughout the entire call, she constantly shouted at me, showing no patience to listen to what I had to say. She outright rejected my opinions and continued to raise her voice, expressing anger and frustration. At one point, she even encouraged me to file a complaint, stating that she was not afraid and that all customers nowadays tend to complain anyway. She made it clear that she had no intention of listening to my explanations, despite my repeated attempts to communicate. This experience has ruined my mood for the upcoming trip, and I am utterly disappointed by the service attitude I received. The representative explicitly told me that current customers are all the same and to go ahead and complain, which she would ignore. Her demeanor and lack of professionalism are not fitting for a managerial position. I am now feeling helpless and deeply hurt by this experience. The issue remains unresolved as she abruptly ended the call without providing any solutions. I believe I deserve compensation for the emotional distress caused by this encounter. I was simply trying to correct an error in my destination, not the travel dates, a straightforward request that should not have resulted in a seven-minute session of threats and hostility. I demand immediate attention to this matter and a satisfactory resolution. Otherwise, I will pursue further complaints through other channels. This is my first and last time encountering such treatment from Trip.com. I expect an appropriate response and resolution to this matter.
