FNB ALLOWING NEDBANK TO TAKE UNAUTHORISED DEBIT ORDERS-CAREFUL IT IS A CUSTODY FEE WITHOUT CONSENT!

I am sick and tired of these unauthorized debit orders that fnb has been allowing Nedbank to place on our account. This happens up to 5x a year, and we have to call in and ask them to remove this nonsense. It is a Custody debit order, no one can tell us who gave Nedbank approval without our consent, so how can Fnb allow this? This is *****ing and Fnb allows it. Most importantly because they allow them, I then get charged an extra fee of R40 for them to dispute this? So they can take money from my bank and bill me for a debit I have no idea what it can be for? I AM SICK OF THIS FNB , SICK AND TIRED OF THIS!!!!
