FNB DOING FNB THINGS

I SETTLED MT CREDIT CARD 16 MONTHS AGO WIHT FNB BUT THEY STILL SENDING INFORMATION SHOW MY CARD AS ACTIVE AND UTILIZED AT 103%. I'VE CALLED THIER COLLECTIONS DEPARTMENT NUMEROUS TIMES FOR A RESOLVE BUT NO ONE SEEM TO KNOW WHAT THEY'RE DOING. I'VE WASTED SO MUCH AIRTIME WITH THIS AND I DON'T UNDERSTAND HOW A BANK LIKE FNB CAN STRUGGLE TO SORT A SIMPLE THING LIKE THIS.
