I understand that a gradplus loan can be repayed in full within 120 days from date of disbursement, and no interest or fees are payable at all on it.  Problem, whenever i call the servicer (fedloans)  to ask how much is full amount, they give me the amount which includes the 2.5 percent origination fee (i.e., 4 % fee minus 1.5 percent up front rebate).  They say they are not involved in the fee at all. They do exclude all the accrued interest, but they know nothing about the fee.  How do I get the origination fee back too?  thanks, Heather.
