<prompt> Human: So as the title says, my wife recently defended her masters thesis which is just 1 milestone in her PhD program. She is still in school and will likely be for another 2 years. However, Great Lakes Loans somehow counted her as graduating this month and her monthly payments will be due starting in June. We did not receive notice of this. Their customer service department isnt open today so we will not be able to contact them until Monday. We had about 90,000 in total as of yesterday. 78,000 was principle and the remaining was interest. Today of course our principle is 90,000 at about a 6 interest rate on average. You can see why Im panicking. Thanks for any and all advice. Edit: formatting  <response>: They should reverse it if it was in error. They might require documentation showing your wife has consistently been enrolled and was never out of deferment.
