I want my money back...

I bought 65' 4k Hisense through Digital Planet around July 2022. Towards end of August it started freezing. I reported it and send videos as proof. Kutlwano who was helping me sent me steps resolve a problem via email. I used it, it did not help. I notified him, he ghosted me. no response to emails. This year March the freezing became unbearable as we could not watch anything for more than 3 minutes without the TV freezing. I reported again. This time Ntando was helping. He told me that Hisense has issued a credit for it. a week later he told me it was a mistake, the credit was for another client not mine. It has been more than a month that we are sitting with a black ornament on the wall, fully paid but not working as now it is totally off. Everytime I call Ntando he says he is escalating the issue but nothing happens. I just want my money so I can buy a working TV.
