TERRIBLE SECURITY AND NO HELP

I have personal as well as business accounts with FNB. My phone and card details got ****** 3 weeks ago and somehow they managed to authorise transactions to the value of R7000. First of all I don't know HOW they were able to do this with all FNB's "security" measures in place. Other than that, they are doing absolutely NOTHING to help me get my money back. I have two active ***** cases for this incident and I've had to follow up MULTIPLE times from my side to no avail. TERRIBLE SECURITY AND HELP FROM THEIR SIDE IS NON-EXISTENT. Would definitely not recommend.
