Debt Busters - Regret the day I answered your call

I contacted Debt busters for assistance because I couldn't take the constant calls, whilst I was trying to manage financially. They debited me R1800 but my creditors still called me asking for payment. When I contacted them they said that they still arranging and the money debited is for admin fees of some sort. I stopped the debits and then received a letter saying my application for debt review has been declined by the courts as my debt of R17000 or something like that can't remember very well was not enough for this process not in those words but that's what it basically meant. Anyway I then decided to settle all my debts in one go with money I unexpectedly received. I called my creditors myself and I did not get settlement amounts I had to pay the full balance which I did. When i got my credit score it's showing zero debt the score went up but I'm under debt review. When I called debt busters I must forward the paid up letters which I did when I called again they told me.that they need to verify that the letters are legit and I need to pay the R3600 to get my certificate and clear my name. What!!!!!!!!!!!! I would rather go to court then pay them a cent.... I feel like I've been ****med.
