Unauthorized Debit Orders

I noticed an unauthorized NAEDO debit order on my Standard Bank account on 13 December, and when I went into my banking history I found the same amount had been debited over the last few months! I called Standard Bank - they told me it was them and that they cannot remove or reverse the debit order. I have a loan with Standard Bank that I pay off at R500 p.m. and they decide to take more money from me by loading a NAEDO debit order of R333 on top of what I already pay. NO communication from the bank to even ask if I’m okay with this. Not only that, it is set for a date that is always before I get paid my salary every month. Disgusting! I am in the process of moving to FNB and I will close my Standard Bank account very soon. Standard Bank’s NAEDO debit order system is *********. Everyone beware of this!
