Ackermans cellphone drama - Premio S84

On 14 August 2021 at around 13:00, I purchased a cellphone from Ackermans, Soshanguve Crossing. The phone I bought was a Premio S84. At first I was very excited to have a new phone as I'd been pick-pocketed a day before.

Fast forward 4 months, the phone will just switch off, even if the battery is on 67%. I decided to take the battery out and I discovered that the battery is actually swollen, resulting in the phone over-heating before it switches off.

I would like my money back as I believe I bought a defective product. Four (4) months and I'm already experiencing battery problems????

I have the purchase receipt and box if these are required.

No, no, no, this can't be right!
