Disgusting service

I went to Game on the 13th Jan 2021 with the bank statement, tv model and serial number as the Samsung curved 55cm just went black and I bought it from them Jan 2018. Nobody has bothered to call me as they said they were looking for the slip of the tv. Today is a month after I visuted their store. The service there is very bad the dont care at all. You stand there for 20 mins waiting for someone to attend to you and you have to tell the story again, I went there 4times and have been told that they are waiting for their head office to sebd the slip. I am so upset with what is happening I have no tv been waiting for their snail service.
