For at least XXXX year, XXXX payments on my student loan have been reversed, with no notice or explanation. I have called the student loan company several times and asked for detailed documents showing my payments and resulting balance due. I have not received the items requested. I have been told both by collections and customer service that they can only submit another " research request '' but can not explain the reversals or offer any documents showing that my loans are being paid down. Consequently, I believe that my loans are not being paid down. I am constantly being called by the company and asked to submit payments, which are then reversed. I need someone at Navient or XXXX XXXX to give me a full explanation in writing.
