Horrible slow service

I bought a 75 inch Flat screen TV last year November during Black Friday. This year October the Tv started giving me problems, the screen was not displaying anything but I could see the TV was on. I went to Game to report and they logged a call with Hisense since it is still under warranty. It took them a week to come have a look at the TV, then they left with it and it has been more than a week now since they took the TV. We haven’t had a TV for more than two weeks, am talking about a TV I bought last year.. this morning I have been trying to call their repair centre to follow up on when are they bringing the TV back and I get cut off twice already. All I want is the TV or my money back cause seriously I can’t continue like I don’t have a TV and how long can one go without a TV… I want my money or TV back.
