My son 's student loans were referred by the XXXX XXXX XXXX XXXX XXXX ( XXXX ) toXXXX Services of XXXX, New York for collection. I wrote ConServe on XXXX/XXXX/XX/XX/XXXX requesting copies for balance sheets for the XXXX loans, showing how the payments I had made for several years had been credited. On XXXX/XXXX/XX/XX/XXXX, they responded with statements of the totals owed for the XXXX laons, but not the breakdown of payments that I had made. I wrote them on XXXX/XXXXXX/XX/XXXX again requesting balance sheets for each loan, so I could ascertain how the payments that I made had been applied. I received no response from them. On XXXX/XXXX/XX/XX/XXXX my son receioved notification that his federal tax refund of over {$1000.00} had been offset at the request of XXXX. On XXXX he received notification that the same XXXX loansad been referred to XXXX XXXX XXXX for collection. I wrote XXXX on XXXX/XXXX/XX/XX/XXXX disputing the debt, and requesting the same information that I previously requester from ConServe.
