very easy call the FSAIC Federal Student Aid Information Center at 1 - 800 - 433 - 3243.
One other thing I'd like to ask about how much of my loan could be discharged if I'm eligible for an approved federal student loans? Who I can contact regarding this matter?
Yes, as I said, only the portion of the loan that the school failed to return is eligible for a discharge. You can contact your loan servicer for more information.
So, how can I apply for an unpaid refund discharge? My school it' still operating.
