JVC 108 cm Mart TV not working

I bought a Television set (JVC 108 cm [43] 4K smart TV) cash on the 26th of July 2025 at Game Soshanguve Crossing. In two weeks, the television set was not working and i took it back to the store. They checked the tv set for any damage that might have caused by a client and found there's no damage. One of the employees confirmed that he had a similar problem with the same set of tv. They referred me to the floor manager Mr Lodwin Mafoho and he (Mr Mafoho) told me that they'll send it to JVC repair. I asked for a new Tv set and he refused by saying the company does not replace the tv. I said to me him " does it mean I paid cash for a second hand tv because if it comes back from repair, it means it is not new anymore. He told me that it's unfortunate because the company cannot give me a new Tv and that is their policy. I wanted my money back to purchase Tv set somewhere and Mr Mafoho said they can't refund me all they can do is to fix that Tv set. I asked for sales manager's contact as he (Mr Lodwin Mafoho) said he (Mr Mohlala sales manager) was not in the office, and they are not allowed to give out his contacts including the email. He told me he is the only person I can talk to and also promised that he will speed up this matter and revert to me in no time. To date he never kept to his promise. I send email to Game lodging my complaint and to date no response. I am not ready to accept a repaired Tv set having paid cash for a new set. I feel that Game is not taking care of its clients.
