I am writing on behalf of my XXXX year old XXXX. She is paying on her grandson 's XXXX XXXX XXXX loan, however they call her day and night requesting that she pay it off in full or they demand a very large payment. They threaten her with foreclosure and lawsuits. She pays monthly and they still call, they even call her on holidays. She asks them to stop calling and has put it in writing and the harassing calls continue. They 've told her they 'll call when ever they want and will continue until she pays off the loan. These calls are making her XXXX and I need to know what we can do to stop this harassment?
