MTN *****ULENT TRANSACTIONS ON A CELLPHONE BUSINESS ACCOUNT

I have a business contract with MTN for 3 cell numbers. In the begining of November 2023 on all 3 numbers we receive notification that our contracts have been upgraded. We queried this with MTN as we did not upgrade our contracts. We were advised that it was a *****ulent transaction and that the upgrade was reversed. It is not January 2024 and after various emails, chating to a MTN business consultant, going to the MTN stores and going to the customer care branch and explaining our situation our accounts have not been resolved. We are being billed 5 times more than what we are meant to be paying and no one has bothered to come back to us or reverse the *****ulent upgrades that was processed on our account. I have put a stop on my debit order. MTN better not send me any threatening emails about not paying the account. We have tried to resolve this. This is disgusting service from MTN. How is anyone meant to trust MTN if they can not resolve a *****ulent transaction
