ESH

There are proper channels to go through when this type of thing happens and you didn't go through those proper channels. Your teacher? I get it. Her brother died and her obligation was with her family - And I can forgive the class "the next day" being cancelled without notice but beyond that it was her responsibility to reach out through the proper channels either make sure her class was covered, that people were aware of the further class cancellations or at the very least sent out an e-mail letting all of her students know she was aware of the midterm issue and she would keep in contact about resolving it when she was able to commit the proper time to it.

Your first channel should have been to e-mail your professor and to allow her to reach out at her own leisure of the course of a day or two. If that didn't solve it your second step would be to go to the department head to express your concern about the mid term.

Having gone through this when my mother died of blood cancer [she was in her 50s and as far as we knew healthy beforehand] I cannot imagine having any desire to take a phone call from someone about work during that time.
