More like Master ****mers

My TV needed minor repairs. The screen went blank with no images but you could tell when it was on from when it was off. Sound was good. They came to collect it to fix it. They did an inspection form to check damages before collection. The tv was in good condition. Two days later they called and informed me that they are not able to fix the TV. I was surprised, but I said okay, it’s fine bring the TV back I will get someone else to fix it. Two days later they brought the TV back and, be hold. The screen had 2 large cracks from the top to the bottom of the screen. Cracks so large that you could get cut if you moved your fingers over them. At the bottom where the scratches start, it looked like the TV was hit with a hammer. I told the guy that brought it back that he must take it back with him to Mastercare and that I will not accept it in that condition. I then contacted them to get clarity on what happened to my TV and the way forward. At first they tried to make it like the TV was damaged like that when they collected it, until they learned that I have a copy of their inspection form. Then this other rude guy from Mastercare told me that I must accept that the TV is dead and that he will put glass on the TV and bring it back but it will never work. I am in tears, I regret taking my TV to those Master ****mers. I want my TV.
