Debtbusters lack of client service

I have been with Debtbusters since 2018 and have never really had any issues with them, my payment was made diligently every month, so I was under the impression that all is well, until I received a phone call from Standard Bank Card division stating that they are handing my account over to their lawyers for collection... As far as my statements I receive every month from Debtbusters, this account was fully paid up, so now began the tedious task of phoning Debtbusters, which the phone is never answered, sent emails to them every week and still to date no reply from them.

The only email I received was from Standard Bank stating that they have removed my account from debt review because of non payment on various months and sent me the statement to verify this. So again another email was sent to Debtbusters requesting answers as to why the payments were not made to that account and again no reply.

I am not used to this type of service from Debtbusters so am utterly disappointed in their handling of my query.
