I Lost ₺24,000 on Trip.com Due to Unauthorized Vietnam–Istanbul Flight Cancellation

On July 16, 2025, I had a Vietnam–Istanbul flight ticket booked through Trip.com. I requested a modification to my reservation—not a cancellation. Despite this, my flight was canceled without my consent, and no verification code was sent to me before the action was processed.

The original listing falsely advertised the ticket as a nonstop Turkish Airlines flight, but after purchase, it turned out to be a connecting flight. That misleading presentation heavily influenced my booking decision. When I tried to adjust my reservation, Trip.com treated my request as a cancellation instead, resulting in a massive financial loss.

Although I immediately disputed the issue, Trip.com responded that only ₺12,000 of the ₺34,911 I paid would be refunded—leaving me with a ₺24,000 loss, all without having used any part of the service.

To make matters worse, I was traveling in Vietnam, with limited mobile access. My Turkcell line had no service, and it took significant effort to contact Ziraat Bank to report the issue. I later learned that the airline's system was integrated with a third-party network, but Trip.com never clearly explained this, nor did they warn that a reservation change could lead to an automatic and irreversible cancellation without OTP verification.

This is an unjust financial transaction—a classic case of misleading advertising followed by unauthorized cancellation, resulting in a large sum being withheld without sufficient consumer rights or transparency. I demand a full refund of the ₺34,911, as I received zero service in return. I also urge Trip.com to revise its reservation change process, include two-step verification for all cancellations, and provide full disclosures when advertising flight itineraries.
