***** on account and FNB unwilling to help

Now have has ***** on one of my employees account going back 3 years and FNB unwilling to supply documentation or help to report this *****. They keep saying that to provide a form they need to speak to account holder. I'm asking for a form not private information. Also they care department say it's not their fault or responsibility to ensure the safety of a customers account. They must be getting a cut from the theft as it seems that only FNB account have this problem. Also they keep getting money from these transactions so won't do anything. KEEP AWAY FROM THEM AS THEY ARE COMPLACENT AND FACILITATE THE THEFT OF THEIR CLIENTS MONEY
