In XX/XX/XXXX ( around XXXX/XXXX/15 ) I called Navient and requested 30-day loan payoff letters for XXXX of my private loans. I needed these letters to complete a pre-approved loan consolidation application with a credit union. On XXXX/XXXX/15 I received these forms online, but there was a big error in one of the payoff amounts - rather than approximately {$4300.00} the letter showed {$43000.00}. The other XXXX letters were correct as far as I know. I called Navient back around XXXX/XXXX/15, informed them of the error and requested a corrected copy of that letter, in addition to new payoff letters for all of my private loans. These were promised to me within 24-48 hours. I still did not have the letters on XXXX/XXXX/15, so I called them back, having a lengthy conversation ( XXXX+ ) with a representative, then her supervisor, explaining the above. They promised a payoff letter for each of my loans within the next 24-48 hours. It is currently XXXX/XXXX/15 and I have not received them yet. 
Here are my concerns : I 'm concerned about the accuracy of the loan payoff amounts on the letters. 
I 've spent a considerable amount of time corresponding with Navient to resolve this. 
While I wait for the letters, interest continues to accrue on my loans - a higher rate than what would accrue if the loans were consolidated, which I can not do until I have the letters. 
If I do n't submit these letters to the credit union for my consolidation application within a certain time frame, they 'll cancel my application, causing me to start over from scratch.
