FNB Business Poor Security and Poor Support on Help

I am with FNB Business.I experienced a ********** transactions on the 31/03/2018. I went to withdraw cash from the Formiss Shell Garage at the FNB ATM on the corner of Alwen Road and Crownwood Road. As i went to draw cash there was a guy who wanted to help me. From the footage one can see that i suspected something suspicious therefore i hid as i entered my password (I done the safe procedure to hide my pin). My transaction then failed and the ATM swallowed my card. About 5 minutes later i get an SMS saying that someone has drawn R3000 from my account from a Sasol garage which is at least 15 minutes away from the Shell Garage. I immediately call FNB to ask block my card. She said that my card was already blocked as soon as it got swallowed. She then said that is she would send me a ***** claim form to fill it out and submit it. She said that i would be contacted within 3 days. I have followed through and completed a the forms and still after 3 weeks i still haven't heard any reply from FNB Business. To my knowledge this is a major security flaw in the FNB Business system. Firstly how did they get my pin, How did they know my limit and how did they withdraw from a place 15 minutes away from me within 5 minutes and most importantly FNB system should have blocked my card on swallow. From my experience in systems, as soon as my card was swallowed ,FNB Should have blocked any access to that swallowed card Id. This is poor show and extremely poor show on their Business Security side. Makes me question their reliability and safety with my business account.
