Don't care about their clients - considering leaving them

Considering leaving fnb as they dont care about their clients and cant show incitive to assist ... I transferred my salary into my loan account instead of my saving pocket in error and now I have no money and they telling me it will take 5-9working days to reverse... I dont even owe on that loan account... I need my money and because of their reluctant to assist me in such a bad position- I am going to leave them. I need to be with a bank that would care in a instance like this and do everything to assist me quickly I mean it's evident I transferred it from my account into my loan account.... why does the loan account even come up for payment when it's paid.
