Worst Service in the Ackermans Cosmo branch

I am so disappointed in the lack of communication and customer service support in Ackermans. Made my first cell phone purchase with them on the 3/11/22,at the Ackermans connect branch in Cosmo city which recently opened up,they convinced me to get the premio step up phone,they didn't have stock and we decided they'd give me the one on display,the worst choice of phones I've ever bought, within 24 hours the phone started giving me issues,from freezing,to a draining battery,and when calls come in I can't see who calls me,and my WhatsApp voice messages stop and start, I asked my partner to get a refund in the same store this morning (before the 7 day warranty I was told about).they gave him the total opposite attention to what we were given on the day of purchase,I understand they had been going through a few issues,but the manager was so unprofessional,so cold towards my partner,gave him the run around and no resolution what so ever,the Ackermans clothing manager was no help either, had to buy a phone today elsewhere but I still want my refund,I refuse to keep a phone that does me no good ,waste of money.
