ATM Deposit Disaster

As I was attempting to deposit cash using Nedbank ATM, a pop-up message was displayed on my screen with an error stating that the transaction has failed and the money has been detained and I should consult the nearest branch. I was informed at the branch that this was a recurring issue and that the branch has informed head office about the matter. I was further advised that the transaction will take further 2 days to be processed, aside from logging a query the teller could not assist any further. I have had my order cancelled as the payment hasn't reflected immediately to the company I was paying and I couldn't provide proof of payment because I don't have one. At the moment I can't be reimbursed by the company I was paying as Nedbank is detaining my money for couple of days with no particular reason.
