Terrible service

I was handed over to MBD by Standard Bank for a Credit Card. This card was settled in full in February 2020, Up until today i am still black listed, as they did not bother to let Standard Bank know that the account has been settled in full. I have not received a settlement letter either.

Trying to get one out of them is worse than looking for a needle in a haystack. on 22 Sept I was told one would be sent, today is the 29th. Still waiting. This afternoon I phoned again, once again I was told it will be sent, but I also need to phone customer care. Phoned them, got referred to another dept. No one even bothers to pick up the phone. No answering service telling you that they knock off at 4. Just waiting and listening to a ringing phone. Even Standard Bank could not get help from them this morning.

I am at my wits end. Do not know what to do anymore.
