Termination of contract

I was approached last month to be assisted with removing my name from blacklisting if I terminate my debt review with Debt Busters. Michelle informed me that I only need to write email to Debt Busters to cancel contract with them. I did so. However, it will be a process for contract to be terminated. I then informed Michelle via whatsapp to terminate telephonic agreement we have until I am done with Debt Busters. That didn't happen. Again this month an agreed amount was deducted. I then explained again that I cannot afford to have two debit orders for same purpose going through. I requested Credit Rescue to cancel relationship and to refund my money. The email address as well as contacts provided do not go through. Please assist by having Credit Rescue refund my money, R1800, back to my account.
