FNB security questions with the call centre

I phoned FNB customer service to clear a error code i received when trying to register for Pay Pal on the FNB online service i I explained to the consultant my issue and told her i am not a client of FNB but just would like to regsiter for the pay pal service on the FNB online banking, she took my ID number and told me the problem was error code and she was going to clear it for me i held on to the call for a few minutes, she returned then telling me she needs to ask me security questions, questions i don't even know or heard questions like" in which province is bryanston " i tried answering but it made no sense to me when i was done she told me i didn't answer the questions correctly i got 50% of the questions correct and i needed 75% now i asked for assistance with a error code and ended up having to take an exam which clearly i failed i explained to her i am not a client of FNB and asked her where do these questions come from she explained from home affairs i asked her now what should i do she said i should go to the branch with my ID so they could verify me, i wasted my time with call a call that one of there agency told me to do on twitter was just to call them and they will assist me never told me of a exam or what they call security questions, take note i am a student with no accounts or credit cards or loans.
