MTN charging for contract after repeatedly asking them to cancel.

I have been with MTN since 2004. I have been using MTN services for 17 years.

I have been renewing my contract with MTN since then, and this year I opted NOT to upgrade. I was still charged for the renewal, and I called MTN to correct this. They said it was corrected, and I was charged yet again. I called again, and I was told that it was sorted. And I was charged yet again.

I have now called MTN more than 42 times and have spent more than 6 hours on the line with MTN. The customer champions have not been helpful at all. They keep referring me to other departments and I have gone around in circles for 3 months.

My number has been blocked because of non-payment of fees on the contract that I did not consent to. I am incredibly disappointed with MTN.
