MTN Bad Service

In November 2019 I app**** to convert my mobile number from a business account to private. All documentation was submitted to the Rosebank Mall shop. In December I was notified the conversion was complete.,However the transfer was never made and for a whole year I have communicated with MTN to no avail. They eventually found the documentation, but refuse to make the change because they say the application needs to be done again with the current date. The problem is on their side, and I refuse to go through this process again. Completely unacceptable service.
