Standard bank SA bad service

On the 29th of July i had a cash jam in one of the standard bank ATM's at East rand mall, i wen't to the branch immediately to report and they told me to come back after five days. On the 5th of August i went back to check if the issues was resolved and expecting to get my cash back but they told me money will be credited, still today my money hasn't been deposited and in the last three weeks i went to the branch five times and they keep on telling me they will call me back until today. I don't know who gonna assist me to resolve this issue if they fail to.
