Incorrect Info

I called Nedbank on 25 Aug 2015 to put a stop payment on my debit order which seems like they changed some details. I called and spoke to a gentleman Meagan. He advised me that the stop payment is still in place for Direct axis. I said to him but the amount got deducted from my account this month. He advised me it should be reflecting in my account again after 24hrs. I must just give it time. I said to him it might be that they changed the reference number to be able to deduct again. He refused to listen and get it done. Now my account is sitting in the negative and now I cant draw money on it and I am being charged rates for everything. If only he had listened and followed my instructions when I called in I would sit with all this mess to sort out now!
