Ackerman's cell phones are defective, and staff are ***********

We bought a Nokia cell phone from Ackerman's 14th Ave Hyper in December 2022 for my son. The store manager did not have stock but gave us a demo model instead. it would not charge immediately and then took about 3 hours just to start up. it glitched badly and the camera wouldn't operate we returned the phone to them a few months ago and waited about two months for it to be returned from 3G Mobile who said they had done a software update. The phone was still faulty, so we returned it again, 3G Mobile sent us a SMS stating the warranty was void due to damage???? and that to repair would cost over R1000.00 or if we declined the repair we would have to pay over R300.00. the slip states we have a 12-month warranty. the store manager refuses to respond as well as the customer care people at their head office they will not honor any warranty and will sell you a defective phone and they simply do not care.
