***** & Compromised Banking details

I don’t know if this is a case of ***** or pure negligence from FNB,I believe that it’s an internal ******** syndicate that’s operating within the bank itself giving out our banking details and nothing is being done to address the issue, from early 2017 I have had to reverse unauthorized debit orders against my account ranging from R99.00 – R150,it stops for 1 - 2 months and then again I’m stuck with the same issue, what I find to be most disconcerting is when I call the bank and the only thing they can do to help is ask you to reverse the debit orders and not addressing the root cause of the problem thus as a client my financial security is comprised and so is my credit record. I need a more feasible solution to eradicate this problem, I need a more permanent solution versus the” JUST REVERSE THE DEBIT ORDER”…….Please Help FRUSTRATED CLIENT OF 12 YEARS…..I Think my Loyalty to the brand is doing me in!!!!
