FNB fails at customer service

I did a cardless cash deposit at Hout Bay FNB ATM yesterday at 5pm and the machine went into "device recovery in progress", and then rebooted itself. No receipt. No message. Nothing. The money was retained by the machine and there is no record of the transaction. I immediately called the helpline who said the only thing to do is to go into the branch this morning, which I did. I was then informed that it will take "3-5 working days to investigate....but they don't work on weekends" What utter nonsense is this FNB? YOUR Machine that we are forced to use for cash deposits (no tellers in Hout Bay and the fee for OTC deposits is much more) goes into reboot, and I must bear the brunt of this? How is that ever acceptable? You charge deposit fees, service fees, withdrawal fees etc etc but then this happens and you're not vaguely interested in asssiting? NOT ACCEPTABLE PRACTICE. I normally promote you as a bank, certainly won't any more. I wopuld like this remedied TODAY.
