Still in debt review because of their error

My last payment to debt rescue was made in Feb and all debt should have been paid.

However they paid monies into incorrect account and have to rectify their mistake as all my payments to them were up to date.

I have been emailing proof and phoning for 2 months rectify their mistake and today i receive an sms that they are deducting funds from account again without a response after speaking telephonically on the phone with them on Friday which they confirmed and promised that they are busy working on the internal problem.

This has been going on for 2 months now. I should have had my clearance certificate in March already and we are going into May.

I still have had no response besides an sms that they are deducting funds from my account again.

This has become a nightmare to work with them. And everytime i ask to speak to the manager Annelien they say they are sorting out the internal error.
