FNB wrecks international transactions.

My International card limits are correct, I am allowed to do international transactions, Yet when a hotel tried to charge my card for authorization, the card was declined, inspite of the fact that I had balance and I lost my booking 6 days before my travel and now I have nothing available.

No one in FNB knows why this is happening and it is happening now for the 6th time that my transactions are not going through when given to international booking sites.

It is the most pathetic service if you need to do international transactions and irrespective of whether you are premium, gold or platinum member of the bank, it never works when you want it to.

I just lost 50k rands worth of flight and other booking plans because of FNB's inability to handle seamlessly any international transactions.

Does anyone know how to legally press charges for compensation?
