FNB branxh giving out customers card details to *********.

Opened up a FNB business account, 3 months ago. Received my bank card, never even used my card, as I don't remember the pin number, card has never even been out of my wallet, as I have only transacted online, for this account, so I get a notification that 2x transactions have been declined for invalid pin, at a place called Afriview , for R9000. So I stopped the card at FNB *****. But it is clear that FNB, has internal staff leaks , giving out card numbers to ********* to commit ***** on customers accounts. I reported this to Northrand road FNB branch manager , but they say there is nothing that they can do. So how do I trust FNB now, to get a new bank card, what is to say that my card details, won't be given out to ********* again.
