Complaint

I bought something online, just to get a message from FNB the next day to say that an amount was processed for which there were no funds and they suspect that it was **********, which I agreed with so that money was never taken from my account. I did found out that an amount of over R3500. 00 was taken off my account that I did not buy or ordered things for. I have been trying to get FNB to look into with no luck. You can not phone there 24/7 phone number for it just rings or no body speaks to a person. I need to get this money back for it is to service my motor vehicle.
