I received extremely poor service from Christiano at PEP CELL Daveyton (Sesfikile Square)

I received extremely poor service from Christiano at PEP CELL Daveyton (Sesfikile Square). On 23 January 2026, I bought a Sylo Future phone which was faulty, overheating and switching off. I returned it on 25 January, and Christiano confirmed the fault and exchanged it for an ITEL AO6s after explaining the RAM, ROM and battery differences. However, once home, the phone was extremely slow, crashing when opening apps, WhatsApp and downloading the Play Store. I returned to the store before 13:30, where Christiano again confirmed the phone was very slow. I was willing to top up for a better device, but after over an hour of testing and despite my valid receipt allowing a return within 7 days, he refused to exchange it, claiming he made an “executive decision.” He delayed by calling a manager, refused to put his decision in writing, became rude, slammed a door in my face, and declined to be photographed. I have audio evidence. The phone remains faulty, and I urgently request assistance.
