MTN Useless

MTN is useless, no better words to describe their customer service. In October 2020 we cancelled a data contract which was way beyond the contract period. We've got a reference number for this cancellation, but still they are trying to deduct money form the bank account. I contacted them on various occasions to sort this out, but still no answers and the debit orders just keep going off. And for each unsuccessful debit order my bank charges me R110 for fees! On my previous attempt the lady told me that she can see that someone on their side tried to cancel the contract but it was never completed. She promised to escalate this and that it would be sorted out. This was about a month ago and still no answers from them. This is absolute **** service and they need to be closed down as they have no idea on how to do business. Further my wife was denied an account at another company as MTN has listed her on the credit bureau. I would like this matter to to solved now and thinking of suing them for all the reversal charges on the bank account and ruining my credit score. They never call you back and trying to call them is a daunting task just to speak to a human. I would never suggest anyone to make use of their service
