Ignoring customers in favour of covering inside *****

Having reported an obviously inside attempt to **********ly extract money from my unused FNB Credit Card, this bank is refusing to acknowledge this & fobbing me of with many reference numbers (11, so far). The unused card was cancelled, on 24 September 2015, but the bank will not refund my credits paid in order to cover its regular standard charges. I've just spent over 2 hours trying to get this money back but was passed from one person to another, just to be told they are "dealing with the matter" Who exactly is "dealing" with this???? The person attempting to de***** my account phoned my wife from an allegedly FNB number! As it appears FNB rather covers up staff problems rather than doing the right thing for its clients.
