FNB SHOCKING!!!!!!!!!!

I do not have the words to express how completely blown away I am with the shocking service from FNB!!! LAUREN LANDY gave me a settlement figure. I paid it. Yet to date i am being harassed by debt collectors ie Daly and Barrett and associates. No one will give me closure on this revolving loan! No one! I've paid the money emailed all correspondence in black and white and 3 months in, I still am being harassed! Can someone just sort this out??!!!!
