Okay. The best thing to do is ignore them when they try to contact you. If you are in need of real help with your defaulted loan, the Default Resolution Group can help you for free.
Anything else, Repayment in full. What if I don't have the contact details for my loan holder and need to make a payment ?
Simply log in and select "view loan servicer details".
Ok, now regarding receiving calls from people who want to charge me fees to get my federal student loan out of default, where can I better find out to avoid these types of scams?
