Disgusted by the service

I deposit money at the bank inside, we first counted the money with cashier and the amount was accurate, but the deposit machine counted incorrectly and my money was short with R 300 this deposit was done 2 weeks ago, till today the bank has not returned my money and thy investigating and I’m disgusted at the fact that thy don’t prioritize their customers. The branch manager is nowhere to be seen. Cresta Capitec has the bad service when it comes to their clients and the machines inside doesn’t count money properly.
