Bad service from Game & Hisense TV screens don't last that long

My 1st Hisense TV screen lasted 27 months, this performance on a 24 month guarantee; just made it. That was in May 2020. Since now a day it is cheaper to buy a new product than to repair an old one, I bought another Hisense, threw away the old one. This new one came with a 48 months guarantee; well, this lasted only 17 months. Doesn't work. I am without a TV for 4 weeks now, since Game, where I bought the screen and gave me the guarantee, is dragging on it's feet. They don't even reply to my emails, let alone get the screen repaired . If you want a TV screen my advise is watch out for Hisense and for Game, keep away from both. Not to be trusted. What is the point in having a long guarantee, if the item brakes down during the guarantee one cannot get it repaired or replaced within a reasonable time frame. Just disgusting.
