YOUR MONEY ISN'T SAFE AND NEITHER ARE YOUR DETAILS

I have had my bank details compromised in the last month, there have been numerous accounts opened in my name and my bank details have been used in these accounts, money has been debited from my account, FNB is aware of this and to this day nothing has aroused suspicion on their side that my account has been compromised. Could they have sold my details to the highest bidder?Maybe. I feel like FNB does not do enough on their side to validate any new debit orders submitted and to make sure that our details are 101% safe and more importantly, guarantee our money's safety. The are very good at sending you information on how you can keep safe, but what measures are they putting in place to ensure that if I tell them once that I have not authorized something, it will not happen again?
