I was turned down after two interviews by a prominent company for an internship, and only a couple days later, I was asked when I had 10-15 minutes to chat today.

Of course, I loved to, so I emailed within just 10 minutes of their email and let them know what times I was available at, and asked them when the best time should be, and if I should go somewhere or expect a phone call.

No reply has come from them since yesterday afternoon, the recruiter wanted to talk to me today. I don't want to lose this opportunity, but I have no way to contact the recruiter other than by email, and the recruiter hasn't responded to my emails from yesterday, even though we were supposed to talk today.

What's the best thing I can do (preferably within the next few hours!) to get the job? Is that even probably why she emailed me, or was a different reason likely? Any ideas?
