Payback the money

On the first off September i withdrew money at a capitec atm in bizana but it came out short luckily for me someone who who at capitec had just help a person infront of me so she was still present when i was doing my withdrawal.she helped me log a call for my problem and they were able to pick it up on the system that the atm did disperse and amount smaller than what i was billed for. I was told someone would call me and no one ever did.ive had to go to the bank numerous times but still i haven't seen refunded my money and now the trips there have cost me more the what im owed.
