Rude and incorrect information

My wife noticed a debit order of R1500 on one of her account at Nedbank. When she queried it they simply told her because she was on behind they decided to take the money from her other account. When asked who gave them authority for this she was told that they have a right as per \Common law to this as Nedbank\". Now I find this very confusing and rude. She had made a promise to pay cash and they went and did as they wish on her bank account. When we spoke to the call centre we asked to speak to manager who took a very long time. She is the one who told u that by common law they can do what ever they want in the customers bank account.<br> When I asked her for the recording she told me I can go to JHB and listen to it I am in Cape Town with my wife. Now I understand how things work I have worked in the financial industry and I have a degree in finical management and I have never head of this way of doing business. My wife has been with Nedbank all her life and she is now considering joining FNB like me."
