Unsuccessful withdrawal reported

On Saturday the 4th April I withdrew an amount of R700 and electricity went off. The atm also went off while waiting for the money to come out. When electricity came back there were no funds out but it reported on my phone... When I went to report at Absa promenade branch they tell me that there is nothing they can do as the money was withdrawn... I need my money but absa is telling me that there is nothing they can do.
