Am I just too anxious?

Hi All,
I applied to class 74 (Frontier) and got the email to schedule my interview. I have called and left a message 2X (last week) and called again last fri and was told that gal was gone for the day. I waited today, no call back. So, I suppose I will try to get her again tomorrow, but that's the 4th phone call and I am starting to feel like a pest!!! Am I too anxious? Or was your experience scheduling the interview the same way??? Sorry for the silly questions.....I am getting sooo nervous, finally at the finish line of applying and I want to get things done.
