standard bank playing games with my money.

On the 16th of January my sister was depositing money with a standard bank ATM to my account. The atm jamed with the money inside so I didn't receive it. She immediately went inside the branch and told them, they gave her a slip with the service request number which they also sent to me. On the sms they sent me it said the deposit will be due on the 20th of Jan. Nothing happened on that date until I went to the branch and they said they opened a case so investigation is still in process. I was told to wait for 24-48 hours, I did that and still nothing happened. I have been calling enquiries for 2 weeks and they always tell me to wait for 24-48 hours. My sister has been going to the branch too and the manager told her she will follow the case but it's been 3 weeks of empty promises and I still haven't got my money. Is it my sister's fault that their atm was faulty and why do they always make me a fool telling me to wait for certain hours. All I want is my money so that I can close my account and open it with the bank that will take me seriously.
