MBD Poor customer service.

MBD has called me more than 10 times a day. I finally settled my debt and have not received any correspondence regarding my paid up letter. They don't take your calls or respond to emails. I have one last account to settle that is also with MBD. Since November last year I attempted to get a settlement letter for Wesbank and to date unable to get assistance. This is causing a delay in clearing my name off debt review. To top it all they are debiting my account every month yet not responding.
