WORST SERVICE EVER

I had a Standard Bank Credit Card and was handed over to MBD attorneys for payment. I paid the account in full during Feb 2020. Up until today I am still blacklisted. There is NO communication between Standard Bank and MBD. MBD did not let Standard Bank know that the amount has been paid, no settlement letter no nothing. I only found out last week that I am still black listed. Trying to get someone at Standard Bank to help is useless. You need to phone call centre upon call centre, not direct lines. One of the calls took 50 minutes and to no avail. They tried phoning MBD while I was on the line, no help there either. I was told they would get back to me. Of course nothing happened. 4 hours later I phone again, same story....... worst service ever.
