FNB Pathetic Service for over 5 years!

I have been a FNB client for a very long time and I am still having a flag on their system advising that I am a risk. It has been 5 years that I have yet to receive feedback as to why the flag is still on the system. I have emailed them numerous times with little to no feedback. Back in 2016 they advised me to speak to NCR, which I did, but they are all giving me the run around, advising me to speak to the other party.

I want this resolved and this flag removed from my name.

They are quick to offer you policies, investments, cellphones, etc which obviously costs money but what if I required either a personal or home loan in the future? They WILL NEVER approve such things due to their own negligence

Please resolve this urgently!!!
