Horrible customer services and billing

n 2018 July/Aug my previous contract expired and I requested MTN through a call centre agent to convert my account to a pre-paid account. She managed to convince me otherwise and cell me a cheaper contract which is my current contract. She said there's a condition that I need to settle my previous account's amounts prior to me moving to the new contract, she provided me with the amount to settle which I paid at the end that month. The new contract kicked in Oct 2018. Months later after many fights with MTN customer service for incorrect billing. I am now told I owe amounts going back to 2017, how do you tell me that my account has been settled and then years later come and tell me that I have arrears from 2017???, Please go back to you phone recordings when I was negotiating the new contract and send me the same records so we can put this issue to bed once and for all.

My phone has been suspended right now due to this, have been on the phone for 2 hours and Sonia Kabelo and her boss Sfiso have just hang up on me whilst trying to resolve this madness.

I need my phone opened right now or cancel this contract so I can deal with a company that understands what customer service is.
