Credit card EFT's

I have been under debt review for a while and as part of the arrangement, my arrears FNB credit card is being paid by the payment agent. In addition to this I periodically also make manual payments. Now this is not the first time I'm complaining on HelloPeter, it is in fact the second time and on the previous occasion the fees charged, were reversed by FNB. The problem here is that my cheque account is debited auotmatically by FNB with a random amount every month. I can't stop these because I bank with FNB. I no longer use my FNB cheque account for this EXACT reason. Now with this happening, my FNB cheque account has gone into arrears by a HUGE amount due to the rediculous fees charged on a return debit. I have quite frankly had enough and this is now my last resort !!!!! If this doesn't stop I will be forced to go to the CCC ....
