Paid up Letter Request

i had a personal loan from FNB, and i went to settle their Loan in May and they promised me a PAID-UP LETTER, within 5 days , i have spoken to over 12 people and logged complaints with them, still nothing, even now, they have not update Credit Berea which was supposed to be done within 31 days, i am really dissappointed with the service i recieved from FNB in this regards. i am forced to come here since i have not been recieveing a letter or any feedback regarding the Cases logged for me and Complaints Lodged from their side by myself. if only i knew, i wasnt going to settle their Loan. This is not the way to treat faithful client FNB.
