GC services contacted me about 2 months ago stating that I defaulted on a student loan 25 years ago. After arguing with them and the board of education I have no proof that I paid the loan since I have no records anymore. I even called the Department of banking in my state to try to find microfilms from 25 years ago but through all the bank mergers nothing exists anymore. I can't even go the school since the school no longer exists. I paid that loan off 20 years ago but can't proove it. Does anyone have any advice they can give me.
