INTERNSHIP!!!!

Ugh! So now I'm out of an internship. I have no clue were my mentor is. I've called, text and emailed, with no success, no replies. I'm delayed now because I don't want for something to have happened to her and then I just blow her off and get a new internship. But then again, if I don't have all my hours by the time graduation rolls around I won't be able to graduate. I don't want to be a super senior because I didn't complete internship hours. So I'm holding out until next week and my search for a new internship will begin. What do you guys think I should do?
