Nedbank refuse to refund me for debit order

I've always heard people talking about how cruel Nedbank is until my encounter with them. I regret the day I opened an account with them and I swear never to go back them again. I went into debt counseling and my debt counsellors send them the notification that I was on debt review but they went ahead to debit me for their debit orders ignoring the other banks' debit order and the fact that I had paid already paid my debt counsellors. For 2 weeks I have been making a follow up with them to refund me since I had already paid the debt counsellors and I'm being taken from left to right. Every time I call they tell me about how they didn't receive my application and when they say they did, they claim that it has been processed. They returned all debit orders charging me R150 yet theirs went through even before my pay day. This is the worst bank ever and it's one bank which refuses to abide by the NCR regulations because what they are doing is against the Regulation if a person is under debt review. I can't pay the debt counsellors and also pay them which they know.
