Lack of communication

I deposited money into one of fnb accounts from the atm, however the machine did not issue receipts, something which is of critical importance yet it's not visible to the client. So when I asked for assistance with the proof, Musasa who is the branch manager promised to assist. But I had to be on his back to get his poorly means of feedback. Which proved to be useless at the end. I was on hold for him for close to an hour just so I can be assisted. How unprofessional for a branch manager. Some people lack certain skills yet they occupy high ranking posts. I am extremely unhappy.
