Poor service at Ackermans - East Rand Mall

I bought a Hisense U965 cellphone at Ackermans East Rand Mall on Sunday 22nd June 2025 and only stated using it on Tuesday 24th June 2025. It was giving problems during that week as it was slow, the battery power lasted for only a few hours and it was not operational at all. I then decided to buy myself another phone which was second hand and knew that I would return the phone I bought at Ackermans and get my money back to buy a new phone.

On Sunday 29th June 2025 I went back to the Ackermans in East Rand Mall to return my phone and explained the issues I had with it. One of the Sales people said the phone has issues and they don't recommend people to buy it, and when I said I face the same challenges, the other consultant who was helping me said there is nothing they can do.

She asked to test it and did so for a few minutes and went ahead to tell her manager that she did not see any fault in the phone.

All I ask is for my money back after receiving such poor service from Ackermans. If there is anyone who can help me with this issue, I would be grateful for their assistance.
