Telefunken TV 39 inch

I bought aTelefunken television from Game in April 2015 with extended warranty. In September lines started appearing on the right side of the TV. Took TV to Game on the 02/12/2017 to be repaired no feed back, phoned on the 08/01/2018 to find out what is happening got told that they have only got back from closing for Christmas and had not looked at the TV. I kept on phoning back and got told they can't get hold of the technician as he is busy. On the 13/02/2018 I get a phone call from Game to say TV is ready asked what was wrong and she said she did not know, got there got the TV and asked if I could test the TV to see if it was working lines still on the side and worse than before, went back to customer services and told Salome that the TV is not fixed then got told that they could not repair the TV because the screen was cracked and is not covered under the warranty. The screen was definitely not cracked went it went in for repairs, after 2 months the TV being with Game still not repaired and worse than it was before it was sent in for repair.
