ATM Query

was depositing money into my personal account at the Nedbank ATM, after working hours on Saturday 2018-02-17, approximately at 16h15, at Eastgate shopping mall The ATM Machine, Terminal no FY75, it first rejected some of my money notes, and I cancelled the transaction, and press the retain cash button, and the atm goes on as though its returning my cash, only to find that that the cash did not come out and then the atm machine, immediately showed the error message and then it reads I must contact nedbank, I immediately without moving, called the nedbank customer line and logged the query, and was given reference number ********** 3 and was told the query takes 6-7 days my concern is that its not my fault the machine did not retain my money, which is R4000.00 , and feels its unfair that I have to wait for so many days to get my money of which I don't have now, I feel my case should have been given a priority and be resolved immediately now Im suffering financial loss and have been disadvantaged of something that was not my doing, and my money is kept and its sitting with nedbank, and been told about procedures, whilst their machines are not maintained and been kept functioning properly.
