Nedbank...must take their clients queries seriously as they promise....

I went to Nedbank The Glen on Monday the 5th of July 2021...To make a deposit at the Atm... But the Atm took all ma money... No receipt to confirm that my money was deposited..l told the security what just happened and he told me not to panic coz am not the first one expirience it so he told to go inside the Bank. I went in the branch to tell them what happened outside... The lady that helped told me.. I will get my money 3 days time..... She gave me a reference number...So today..on the 7th l received a message saying that my query was declined.. All my money is gone just like that... I called back to try understand the problem the lady told me that she is sorry that this is happening... And she never said anything about my money.... So l lost my money just like with Nedbank... Please Help....!!!!....
