Getting charged bank charges although teller claims I have funds available and when trying to draw I'm told there are no funds available???

I had R200 deposited into my banking account.

What started with R212 available, is now down to R185 as when I try and draw this money which is nearly R20+ less it tells me the funds are not available..

Its a saturday afternoon, and as can naturally be assumed, no service, but I'll continue to pay the bank charges... Its actually a joke. Peoples bank..... I lost my job some years back, and as a result of failed debit orders, an astronomical amount was paid to Absa, and after going in to see them, I was told, sorry, can't help you.....

You'd expect something more from a bank claiming to be the peoples bank right?
