DMC IS ********* AND RUDE WITH PRESCRIBED DEBT

I had a Blue Bean Credit Card and went under Debt Review in 2016 and according to Standard Bank the account was excluded from Debt Review but not according to Debt Rescue and Standard Bank said the account was outsourced. This debt with DMC prescribed in the mean time and when I phoned for a paid up letter the consultant said my account is paid up and I must phone *** for a paid up letter and after phoning for days on end they said I must phone *** again and then another consultant said must get clearance from team leader if debt has prescribed and will phone me back never phoned me back and I have emailed them no reply. I spoke to DMC on whats upp this morning and explained to them that I either need a paid up letter or prescribed letter and they asked did I pay the account and I said I was under Debt Review and Debt Rescue paid this account every single month and they politely told me phone Debt Rescue for a paid up letter. They are very rude and unhelpfull and if this debt has prescribed I will email complaints at NCR to report them because they are ********* in each and every way and they know for a fact that it has prescribed but they still do not want to assist you they can go and listen to their recordings because you are warned every time that calls are recorded for quality and what ever reasons. Their consultant said paid up and the other consultant said prescribed debt. I insist on a paid up letter from DMC or they must send my stuff back to Standard Bank.
