Ghost debit orders haunt my account

I don't know how many times I had to ask FNB NOT to let any debit orders go off my account except for three (3) I have authorized, having to dispute debit orders every month is not my idea of banking really, or is this one of FNB's plans to milk cash from us poor customers because we get charged to stop debit orders? I'm really fed up with this service you know, we trust our accounts are handled by professionals not armatures. I am very disappointed that a very big and reputable company can't solve a little problem like this one, do we always have to run to the media for us to be heard really? it seems when we complain internally our complaints are being directed to a dummy place somewhere which is very irritating for me as a customer.

STOP ALLOWING DEBIT ORDERS FROM MY ACCOUNT EXCEPT THE 3 I"VE AUTHORIZED, simple as that.
