Unauthorized debit order

I received an sms on Saturday the 09th may 2015 from Absa stating that Absa has transferred money from my savings account to my credit card and i immediately contacted Absa on the number *** to find out of what was going on and the consultant who spoke to me informed me that yes indeed Absa transferred money from my savings account. The consultant informed me that I must go to any Absa branch to have my money reversed of which I went to Absa branch in four ways yesterday and the consultant told me that my money could not be reversed. 1: I was not contacted by anybody regarding the debit order. 2: according to Absa they say it's for a credit card I had in 2005 it's now 10 years later and Absa deducted money with ought my permission. I would like Absa to refund me back my money or I will contact the banking ombudsman as according to consumer protection act, Absa has to contact me first before they do any unauthorized debit order on my account. My Riggs were violated and would like my money back
