utterly disgusted - unauthorised debit order

Hi Peter, I'm extremely disgusted with African Bank. On the 16th February 2016 a debit order of R2142 was deducted from my account by African Bank without making any arrangements with me. Initial arrangement is he 25th of every month. I phoned African bank and reported the issue. 1st person named himself Sipho Gama who logged a dispute for me, and told me i will receive my money the following day. That never happened i phoned in again and Spoke to Daniel he never gave me hi surname. He confirmed that Sipho Gama doesn't exist and the Ref number: *** he gave me was invalid. The so called Sipho Gama his real name is Mathonsi. Today again i phoned to confirm when am i getting my refund, from a supervisor Lumko Mpande. He told me they can't reverse the money they've closed my account. No one bothered to give me a call and advised me on this or update me on my dispuse. Instead the resolve it amoungst themselves Who authorized them to debit m account on the 16th. January debit order went on the 25th. I want m money b end of business today.
