TV 49" CURVE

I bought a TV this year March at GAME MALL OF AFRICA, around May this year TV develops a line on the left side of a TV, I took it back to game immediately, game took it to MM All electronics which said I must pay R7000 to repair a screen as warranty doesn't cover a screen, I then told them to bring back that TV because I can't buy 2 TV in a period of 2 month, then my TV came back broken on the frame at left corner of the TV "pictures available", I then told them to take it back to repair a frame, All electronics they then discovered that a transporting company are the one that broke my TV, they agreed to pay for it, all electronics give them a quote of R1000 something for a frame, transporting company they then went to all electronic to fetch a TV as a quote is high for them, they took my TV to their back services without my acknowledge, THEN NOW MY TV IS BACK SCREEN IS DEAD NOT SHOWING, I TOLD GAME TO GIVE ME A NEW TV THEY REFUSED, THEIRS THIS GUY BY A NAME OF GRAHAM STORE MANAGER, HE'S RUDE TO ME, SAYING IF I DONT TAKE MY TV HE WILL TAKE IT AWAY "BIN"
