Why do I even try to stop a Debit Order

I was forced to go under debt review this year. So I cancelled all related debit orders. But once again, problems with both Nedbank and MFC (nedbank). Full of excuses about paperwork and passing the buck, I am now left with two children at home without food on there table, and in a constant battle to get any answers as to refunding money taken from my account ********ly. It is so easy for the bank to take money without any regard to the customer and then sending the customer in a constant loop, to try and salvage his own funds. But I gess we al have 'All day\ "Every day\"" to battle these kind of issues. Severally upset and disappointed customer!!! """
