Standard bank needs to up their customer service game

I deposited money on an Atm to a wrong acc, I than went to standard bank Hillcrest Corner branch with all my documents and the consulted took the slip and checked the account I deposited into and found that the money was initially deposited into it. He told me he couldn't give me their details because of confidentiality claus and I understood and that he will try getting hold of them, I kept phoning the bank every week for the progress with no luck, until a month later I was told they couldn't help me. I sent an email to their customer support, no response. This is my hard earned cash, how can they just say they can't help when they have all the details and won't give me either.
