ok, another question, how can I request the cancellation of the unpaid refund if the school is open?
You should be able to contact the school and attempt to resolve the problem with them before applying for an unpaid refund.
What if I am parent who received a Direct PLUS Loan to help pay for my child's education, will my loan be discharged due to unpaid refund?
Actually, yes, the amount the school should have returned will be discharged.
