Campus Rep Interview - did not call during my selected time slot?

Can anyone offer any help. I am freaking out right now. I scheduled between 130-230 for a phone interview as an Apple Campus rep, and they did not call during my time slot - and now I have an exam in 30 minutes in case they are running late. The website where I registered has no contact information.

I know it is ironic to discuss on a rumor forum but I have no clue what to do, this is a phone call I have always dreamed of getting :/

 

Thanks guys, it was a marketing exam and the professor frequently uses apple as an example in class - so I spoke to him before and stepped out for 5 minutes to reschedule.
Thanks again, I was just super anxious at the time lol
