PICK N PAY IM SO DISAPPOINTED

On the 6th of February 2024 I went to pick n pay hyper Maponya mall and bought a Demo TV 55inch Hisense for R7200, the TV worked for only 3 months, on the 22nd of May it stopped working I then decided to take it back for a new one, spoke to Tebogo and he the called his superior who then refused to give me a new to TV even though I said I'll add another amount for a new on e because I cant allow it to be repaired as it will give me more problems going forth. They refused to refund me my money, while we were busy tackling the situation I collapsed in store and was not in a proper state to continue with them, they took my slip and TV and said they will get back to me till this day I have not heard from pick n pay. I'm so disappointed that this is how you handle your customers, can I please get my refund or a new TV.
