Direct Axis can't effect debit order???

I recently changed from FNB to Capitec bank. Banking details were confirmed with Direct Axis on more than one occasion. The debit order is not deducted at all as requested. I have spoken to several agents to effect the debit order. Last month I payed bmo an EFT after Direct Axis could not resolve the problem. This month is the same problem. Direct Axis claims that there is no funds available. This is nonsense. There is more than enough funds available. Now an agent from Direct Axis phones me to say that my account is in arrears. I requested Direct Axis to cancel the debit order. I would rather pay bmo a EFT, but this they refuse to do. PATHETIC.
