unauthorised debit

I have a FNB gold credit which is unfortunately in arrears.on Tuesday FNB decided to debit R9000 without considering how much can I afford.I phoned the collections department and spoke to a heartless arrogant woman called Lyvone Jordaan who promised me that her controller will get back to me.<br> <br> All I need is my money to be reversed And properarrangements made depending on how much I can afford.<br> <br> I find the conduct of your collections department very unprofessional and *********.this is theft to be precise!!
