Poor customer service MTN South Africa

Since March 2022, I am trying to convert an existing month to month contract to pay as you go. Every time I get a promise from the consultant that it has been sorted, just to find the debit order is still going off at month end. Even with email correspondence I had no joy. It is delivered and read, but absolutely no response. MTN has the worst customer care that I have come across. I do not know how to get MTN to respond!!!!

Just absolute poor inefficient service. But I suppose you can not call it a service
