Worst Service!!!

I got a contract with MTN in January 2021. The contract was supposed to expire on the 31st of December 2022. In September 2022, I went to the MTN store at Alberton New market, to ask what the procedure is for making sure the contract is cancelled on the day of expiration. Their agent told me I needed to call retention and tell them to cancel. In October 2022, I called retention to get them to cancel it. But I was told I needed to call one month before the expiration date. In November 2022, I called MTN retention department and told them I won’t be continuing with my contract after the expiration date. The record of that call is in their system as I was told by their agents multiple times when I call them. End of January 2023, they sent me a statement which showed the contract was not cancelled as communicated and debited money from my account. I called to ask what was happening and the agent I spoke said he doesn’t know why the contract was not cancelled because it does show that I did communicate that I won’t be continuing with it. He also said he would escalate the matter to his seniors and they will get back to me after their investigations. I then went to my bank to reverse the payment and blocked them from further debiting my account. Towards the end of February 2023, I got another statement still showing that the contract is still active and I called again and even asked to speak to the agent’s supervisor. I spoke to the supervisor by the name of Mumtaz Ismail. She gave me her email address and asked that I send her an email detailing what happened of which I did on the 24th of February 2023. She never responded to me and even acknowledge receiving my email. On the 8th of March I then followed up via email on the progress and she still didn’t respond. After that I have called countless times to try and reach Mumtaz and also follow up from the MTN agents and why my contract is still not cancelled given that I am still receiving statements. But there’s always reasons on why they can’t transfer me to her, with promise to get her to call me back and that never happens. The agents I have spoken to all just say they will escalate the matter for investigation but I never get any feedback. On the 25th of May 2023, I got a message that my account has been handed over to Vericred (given that I am not paying the accumulating bill). The Vericred consultant called me and I explained the matter, she said if I still don’t pay the balance, I will be taken to the credit bureau. I then tried to reach out to MTN again but there was no assistance.
