I have called and waited on hold for over an hour, emailed several times, and been into the office at Gateway. I turned in my deferment form, was told that it "looked good," and that I would be updated in the next one to two weeks about whether it had been accepted. It has been over a month. I have tried contacting in every way imaginable. I have received multiple letters and emails saying my loan is delinquent, but no confirmation or denial of my deferment form. My deferment was for a graduate student grant, which I am now on in Bulgaria, so I cannot get in contact other than through email, but have still not received any sort of confirmation that they have received any of my five emails over the past month. They will destroy your credit for no reason! Avoid at all costs.
