Turkish Airlines Ticket Cancellation Despite Same Day Flight Availability

I experienced an issue with Turkish Airlines and Obilet. Months ago, I purchased a ticket from Muş to Istanbul. As a private sector employee, I managed to get only a two-week leave for my wedding. After the wedding, I received a message that my morning flight for the following day's vacation was canceled and rescheduled for the next day. However, I later found out that this rescheduled flight was also canceled. Despite having another flight on the same day, my ticket was canceled without informing me about the price difference. I suggested boarding from Diyarbakır, but since I had booked an economy class ticket, they said they couldn't change it and could only cancel it. Even though the cancellation happened on the same day and it wasn't our fault, no assistance was provided. Obilet redirected me to Turkish Airlines, and Turkish Airlines said that since I booked through Obilet, they were responsible. As a result, we couldn't go to the hotel we had paid for on the happiest day of my life. Despite having a flight on the same route on the same day, no help was provided. Brands that hide behind their corporate identities and advertise did nothing to resolve our issue, even though they had the means to do so.
