MTN IS USELESS AND NEED TO SORT AOUT THEIR ACCOUNTS DEPARTMENT.

I have been a customer with MTN for over 10 years. From January 2020 to May 2020, I have been making my MTN payments via the online credit card payment option. Somewhere along the line, they stopped allocating the payments that have been made showing that there is an amount outstanding on my account. For June's account, I noticed the outstanding amount and contacted MTN to rectify by sending proof of payments for the entire year to 4 different consultants as well as the billing department. During one of these conversations, I asked a consultant to load a debit order stating end of July to try and avoid the allocation of payments in future. After speaking to this consultant, he notified me of an amount due for June month without the unallocated amount. I immediately paid the amount owing for June, but then a few days after MTN prematurely debited my account for the full outstanding amount. After trying to rectify everything again, MTN now advised me of an even larger amount outstanding. They cant assist me to stop a debit order for the wrong amount and the so-called manager never phoned me back. I have been struggling a month now and cannot believe that I am being ignored or not helped. MTN MY ACCOUNT IS UP TO DATE AND YOU ARE SITTING WITH THE PROOF OF PAYMENTS!. Also, a have a large variety of order/ticket numbers but yet no action takes place on these. THIS IS PATHETIC, YOU ARE *****ING MONEY WHICH I DO NOT HAVE AND I HAVE MADE ALL PAYMENTS AS PER MY ACCOUNT. I hope I can get help here, because it is impossible to speak to a manager or the billing department.
