Poor after sales service

Pity there is no zero rating. We bought a Samsung 55" tv during March 2023. In June 2024 my wife went in to the Game store in Bethlehem to complain about the tv having lines on the left bottom side of the screen.The lady at the customer counter took her details and asked for the proof of payment. As it was very faded, she asked to keep it and she will get back to us. The next day I received a call from Game asking for the serial number. I said I would have to remove the tv off the wall to check the serial number. She said she would call me later but she never did. On 12 of November in the evening the tv just went blank. And would not come back on. My wife phoned Amos at the Game in Bethlehem and informed him of what happened. He said there was no complaint logged and that we need proof of purchasing the tv from them. After a long battle phone calls back and forth and eventually ending up that I phone Games customer care and complaints a request was logged to Samsung by Game in Bethlehem. The manager was very rude when I contacted him and he was not very helpful. We have now been without a working tv for a week and no joy. This is not acceptable. Game service sucks. Can not get hold of Egon from Game customer care and he is not returning my phone calls. Useless
