R2500 Swallowed at Nedbank ATM

I am incredibly dissapointed with Nedbank. My Father worked for them for many years. Almost his whole working career and have had my accounts with them since I was young. On Friday 22 March I went to the Cape Gate Branch to deposit R2500 that my child had saved up for himself. The ATM malfunctioned and swallowed his R2500 with no slip or reference or anything. I went inside and was told that I would now have to stand in a very long queue to report the matter. With my child, who was crying. Which we did. We received a reference number and I have phoned the call centre multiple times since then with no result. As of today 11 April that amount has not been returned to my account almost exactly 3 weeks later. In fact they turned it down, and had to re-open the case after I phoned again because they assumed than an EFT of R2500 made close to that date was the money from the ATM. I mean, the difference between an EFT and cash deposit should be fairly obvious. It is ridiculous that they have not been able to resolve this and I shall certainly be moving my accounts elsewhere.
