ATM DEPOSIT

I made an atm deposit of R700 at satndard bank mahube branch on the 4/11/2015 and the was a technical error , the ATM took the money and gave out the slip that says technical error please contact your nearest branch then i went into the branch to lodge a compalin then the branch manager sad she will follow up , a week passed and no one contacted me to give me feedback I went back to the branch then the lady called Pertunia sad they robed me outside because they didnt get my money they only got R250 and it doesnt belong to me ,so in other words they say i am liying I didnt make a deposit.I told them that how can the atm give me a slip if I didnt make that ATM deposit .Till today nobody contacted me with my refund
