MISCOUNTED NOTES BY ATM CASH DEPOSIT

Today, I deposited money at an ATM about R29 600 with R20 000 comprising of new crisp R200 notes which I also found hard to separate when counting. The ATM only authorised R19 600. Miscounting a whole 10k. After receiving a notification on my phone I realised that 10k was miscounted. I immediately went into the branch and lodged a dispute. I was informed it would take about 24 hrs, I received a text saying my dispute was unsuccessful. How can they confirm before they have counted all the money that was collected from the ATM. I’m not impressed with the service, but I promise to take them on until I get this money which to pay a shortfall on my dad’s estate. I can’t believe this bank after so many years banking with them. I’m so furious and going back tomorrow and everyday until I get my mother’s money back.
