I took out student loans with XXXX XXXX financial to help cover my college tuition. 
The loans were later converted to Navient. After repaying on the loans for over XXXX years I saved enough to pay off the account. In order to ensure that the payment was handled properly I called their customer support line and their agent informed me of the payoff amount as of that day and that it could take up to XXXX days for the account to show paid in full. I made the payment at that time per their instructions for the posted amount. 
After XXXX days I have now been informed that they will not show the account as paid in full for up to another XXXX days for the account to show as paid in full. Please note, they changed the terms of their agreement XXXX days after the payment was posted and now claim they have up to XXXX days to show an account as paid in full. 
The loans in question were for XXXX University and the University XXXX.
