Nedbanks poor administration, my problem

I woke up to an sms informing me that Nedbank has debited an amount of about R1840 from my account. So I call them and I'm pushed from person to person until I ran out of air time. I recharge and call them again the same thing happens until I'm told that I have a loan with Nedbank, which I don't and that that debit order is for that loan. The Lungile lady that I spoke to last admitted that it was an error in their side and Nedbank is ver apologetic for the error. They will refund the funds on 08/01/2016. My biggest problem with that which I communicated to Lungile is that I can't wait that long for an error that the bank made not me. I need my money as I have things to do with it. Lungile brushed me off saying Nedbank can't assist I will have to wait until 08/01/2016. Nedbank took my money ever so easily and now they can't return it immediately? Where is the remorse in that? Nedbank is not a people friendly bank, they have no compassion. They made the error and yet now they are not willing to rectify it with immediate effect although they have the means and capacity to do so. I'm moving my Acc to Fnb and that's why I closed my Investment Acc with them..... *Fed up for centuries*
