XXXX XXXX is harassing me for payment of my son 's student loan. First, they went through XXXX, now a law firm in New Jersey, Schachter Portnoy, LLC. My son has been paying this loan through XXXX for many years. They were accepting his payment up until XXXX, 2015 when they returned it to him. His address is on file with the loan companies ; however, they are still sending letters to my home. He has n't lived in that house in over 8 years. XXXX is willing to pay the loan, but no one has returned his calls or contacted him. They are just threatening me. I return his letters to them unopened and tell them to mail it to the correct address. His forwarding order stopped from our house years ago. I do not appreciate the threats and these collectors telling me the loan is in default. He has been paying the loan in good faith and all he received from XXXX was the returned check. No other information was provided to him as to who to contact about this loan. When XXXX took over the loan from XXXX and XXXX, the first thing they should have done was contact my son prior to proceeding with the collection process. In turn, this is unfair to my son and myself.
