UPGRADE AND NO HELP AT ALL DUE TO FAULTY PHONE

I have been a client with MTN for more than 20 years. This year i decided to upgrade via online due to covid and didn't want to go into a store. Received my phone on the 18 August 2021 phone is faulty. Went to MTN FESTIVALL MALL was told I need to go to another store or contact the call center to collect the phone and replace it. Phone the call center on 19 August 2021 5 TIMES every time different number, was told that i can go to ANY MTN SHOP and they will replace the phone. Went back to MTN FESTIVALL MALL and was told they cant do it because they are a franchise. Phone the call centre again and was told 6 different numbers to contact just to cancel the contract now. I have never experienced this *********** service in my whole life. If you deduct the money for the upgrade I will be returning the debit order. Will need to try again to have the contact cancelled. Goodbye MTN
