Samsung 75-inch TV Remote Malfunction and Support Delays

My ordeal began on October 8th, when my Samsung 75-inch TV's remote control failed. I immediately called customer service, and they assured me that my service request had been registered, with a resolution time of 48 hours. However, when I called again on October 11th, I was told it could take up to a week. I reluctantly agreed and patiently waited. Today was the eighth day, and I called again, only to be told that the service request was still open, but they had no idea when the remote would be sent. When I requested to speak with a supervisor, they promised to contact me within two days. This service experience has completely frustrated me. I spent a significant amount of money on a 70,000 TL TV that isn't even a year old, but the remote isn't working, and I'm stuck in a loop of waiting with no accountability.
