Trendyol Order #2796399840 Unfulfilled After 1 Year

I made a purchase from Trendyol on August 22, 2023, at 09:45, but even after all this time, as of August 07, 2024, my order remains unfulfilled. Whenever I make a call, I am able to get through to them, but unfortunately, they never bother to respond to me. I made a request, but it states that I can track it in my requests. Unfortunately, my requests are not visible.
I would appreciate some help in resolving this matter and receiving my order. Your delivery number is 2796399840. Thanks a lot.
