Over payment and can't recover my money

I have been under debt review for almost 2 years and National Debt Counsellors (Hyphen) have been handling my payments. I discovered in July that the balance that they say I owe in they statement was not accurate it was R3000 more than what I owe. I made an enquiry on my own requested balance statement from my creditors and informed my counsellor to look into the matter. He was giving me a run around telling me that the administrators are busy sorting the matter out. Then came month end they debited my account and "told me" that they payed FNB R2080 whereas I know that my balance for FNB was +-R300. Now I need them to get a refund from FNB who they say they paid they are telling me to go to FNB and find out for myself cause FNB say that there was no extra money payed to them. I am so frustrated with they service, I did pick up that this was going to be a problem but they ignored me and now my +-R1600 gone and I don't know who I am going to get it from. National Debt Counsellors and Hyphen are the ones who are suppose to recover that money cause they are the one who made payments on my behalf.
