Navient Student Loan Complaint

Navient Student loan department,

Non-federal student loan Dealing with my lender or servicer Trouble with how payments are handled Louisiana

I have made several additional payments to Navient on my student loan. I elected to have these payments applied to the loan principle. I noticed that on at least - occasions these payments were applied entirely, or partially, to interest. When I contacted Navient they told me this was done because the loan was past due, which was not true. It clearly states on the payment history that there were not late payments, as my minimum payment is automatically drafted out of my checking account each month. I pointed out that I could see at least - consecutive payments prior to - such occurrence of the payment being misapplied. After I was lied to by the representative, I requested to speak with a supervisor. The representative originally denied my request, but eventually connected me to a supervisor who informed me that she was unable to even see the additional payments on her system. The supervisor identified herself as - # - on -/-/15. I took screenshots and emailed them to her, and she acknowledged receipt of the images and stated that she would look into these payments and follow up with me when it was resolved.
