VODACOM PMB - Brookside Mall

I took a contract with Vodacom Brookside Mall in Pmb on the 28th of February 2024. The phone was a samsung galaxy S24 Ultra. When the guy opened the phone it started to heat up. I was told to try it for a day or 2 and then see if it still heated up. The phone then did an update and requested a pin without any simcard inserted which was strange. I took it back, and the phone was reset. It continued to heat up so I returned the phone. I was told it will take 7 to 14 days to be checked for OBF . It is absolutely ridiculous that the phone was not replaced immediately. All I get told is the matter has been escalated and they will revert. It is a brand new phone, I then got told that the phone came back and had no faults and cannot be replaced. Up to date I haven't received feedback after requesting the phone be replaced immediately. I am paying for something brand new, it is unacceptable that I should pay for a phone that heats up and has faults. Absolutely poor service received, highly disappointed!!!!
