FNB no one stop service.

My wife tried to draw cash from an ATM using her credit card. It was declined. FNB sent me an SMS which states: "Transaction declined due to foreign expenditure limit exceeded. Call ***." This was very worrying as I have not had any foreign expenditure and what has drawing Rand cash from a local ATM got to with it. If you phone the number given in the SMS nobody can help you. They tried to put me through to the Forex department and cut me off. I phoned a second time. This time they put me through to premier banking but I ended up at private client banking who also referred me to the Forex department and pug me through. The Forex department could also not help me and put me through to another department that supposedly deals with credit card limits. They also were clueless and put me on hold permanently. I then gave up after half an hour of a phone call I was paying for. This is terrible service. I no longer want to bank with FNB.
