Debit order *****

It has been fourth month ever since I have been fighting with FNB to stop ******* debit orders from my account. There is one debit order from so called Clientele that I call them to ask them stop it. It cost me R30 airtime as well reversal fee to reverse it. I don't have anything do to with Clientele. This month the debit order went through once again they are expecting me to do the same it did three months ago. This is too much for me. I feel this is scheme for them to make money. We can't be doing same things every month. I will take this to the ombudsman as well
