MTN has kept both the phone and my R5000 since June 2024!

I walked into MTN store at V&A Waterfront and spoke to the sales person Amanda. Told her I want a phone that is 5G compatible and also functions well with Apps. She referred me to an instore HUAWEI salesman whose service was pathetic he kept disappearing while serving me he would disappear for minutes on end while getting my new phone up and running. Little did I know that the phone he sold to me was not what I clearly told them I want. I returned the phone to them he fiddled with Uber App and sent me away with a message that he has escalated the matter with his manager. I received no feedback until I went back to the store as the phone still did not pick up the 5G network. They took the phone in with an incorrect description of the problem. They said it is slow and heating up! And I saw this only when I got home. 10 days later no feedback until I went into the store again. Only to be told that the technicians said the phone is not slow and not heating up! Of course it was a lie from the store! The phone simply did not connect 5G network and the Uber App was dysfunctional. So I just left the phone with them as they did not want to refund me. It has been a year now since they have kept both the phone and my R5000! They keep changing the area managers as well so the issue is forever new with the store. I want my my back! MTN is the most *********** and unreliable service provider.
