ATM failed to dispense cash after withdrawal

I don't know where to go now. I called about a saswitch transaction that did not pay out the withdrawal that I tried to make. The transaction was on the 10th of July. I called the 0860 number on the 13th of July to report the problem. (***). I have not heard anything since then and the money has not been returned to my account. In all my years as a Nedbank client, this is the worst service ever. It's like they just don't care.
