Here's my plan for Monday so far:

I plan to email the completed deferment form and all documentation to Mr. S since I only have his email. If his response indicates that I'm all set, terrific! If he says to call him, I will not call. I will instead mail my deferment form with delivery confirmation*. I may have to suffer a late fee, but so be it. I might also try to call the loan office hoping someone other than Mr. S might answer. If Mr. S answers, I can simply hang up. In order to protect my sanity, I will lie and say that the call just got disconnected if asked about it. I don't lie unless it is a last resort for self protection. That's about where I feel i am, left without other options.

*If I send it in the mail, I have all month to try to get on the phone with a non-Mr. S, but I will have to find someone to confirm the approval or denial of my application.
