Dispute

On the 10th of March I Went to an absa (on site), atm at the Glen to withdraw cash with my woolworths credit card,Atm did not dispense cash as atm gave an error saying atm temporarily unavailable got a receipt and received an sms stating that I have withdrawn, went inside the branch to load a dispute, ***** department called the next day stating that the cash will be refunded within 48 hours, today is the 23rd of March and still hv not received my cash back, iv called I think 4/5 departments and I'm being moved from department to department. I'm clueless something that was said to take 48 hours nd it's now 10 working days. I'm even tired of calling nd I don't even hv a reference number!
