Well, OP, what I would do is send one last email. Use regular sized font for everything but this (use the caps and color the font and increase the font size) :
I CAN NOT USE THE PHONE, NOR DO I WANT SOMEONE TO SPEAK ON MY BEHALF. PLEASE EMAIL ME THE TIMES YOU HAVE AVAILABLE FOR AN APPOINTMENT. IF I DO NOT GET AN EMAIL FROM YOU, I HAVE NO CHOICE BUT ASK THE DEAN TO HELP ME.
I would CC copy the Dean.
HTH.
