ATM FAULT

Yesterday 29-08-2015 I went to an atm at Calswarld to withdraw R500, the atm is still giving an option for withdrawal yet when I selected the amount it was deducted from my balance though no money came out. I called in to report this immediately and was told that this either rectifies itself within 3 hours or I have to wait for 7-14 days before being reimbursed. This makes no absolute sense to me as the atm shouldn't give an option for withdrawal if it's out of money and the withdrawal happened immediately but I have to wait for my money for that long. Probably you should ask FNB what happened when they started messing with my money. It seems the big banks are the way to go as I tried using an FNB atm but options for withdrawal weren't there as clearly the atm is programmed correctly. What would have happened if this was my last cash and I had an emergency? I had to resort to using a Nedbank atm as I needed to make a deposit to an FNB atm and was obviously charged R8 which I want back and I will be changing banks to Absa I can't get such headaches from a bank really..... Pay Back My Money!!!
