duty of care

I went to standard bank in alexandra to deposit a sum of R3000 around 15:30. When I got there the bank was closing so I had to deposit the money in the standard bank atm. I followed all the prompts untill where it opened for me to deposit. I deposited the money and the machine closed. While I was waiting it said transaction cancelled. No receit was given. There were still people inside the bank and I called them and the lady told me to csme tomorrow. I know they could hsve checked it then and there. I just hope I didn't lose my money. I called customer care and I was given a ref number. I was told that they will investigate and came back to me on the 11th of june. If someone cared I think I could have been put at ease.
