Stinking customer service from Pep Cell Maponya Mall.

I bought a phone on 12 July 2023 from Pep cell Maponya Mall and noticed 2 days after purchase that the phone only rings when receiving incoming calls,sms and WhatsApp notifications (tone only no vibration) I was only able to bring it back today July 25th due to work commitments.The guy who was assisting me was incredibly rude,he was shouting at me like a stupid child in front of other customers.He repeatedly said " It's not my problem what do you want me to do?It's either I book it for service and you'll get it back 4-6 weeks from now or you keep your phone cos the 7 days grace period has passed" Then I asked for his senior or for him to call customer care and I'll speak to them,he rep**** " Our store phone is not for customer use you have to use your own phone and airtime to escalate your complaint ". I opened this Pep account in June and used it to purchase this faulty phone that they refuse to exchange or refund after using it for only 14 days and I deeply regret it,if I could I would've closed that account TODAY and never shop at Pep again.Never have I been so disrespected and received such poor customer service and made to feel like I'm inconveniencing them for returning a faulty product they sold to me.Staff at that Pep Cell Maponya Mall branch need a refresher course on customer service and how to communicate with people in general...Pep has definitely lost a customer in me from that moment forth.
