Why don't they have actual people answer the phone?

Agreed. Checking online would be better. You Should be able to find phone #s for the various departments, including hiring. As for answering directly, there are not enough employees at the theater to be on the phone constantly.

I was try to ask if they were hiring at all

You would probably be better off going online to ask the corporate office that question. Was there something specific that you wanted to know about the theater or was it just theater times? Because of its theater times those are always listed online and they're usually more accurate and up-to-date than any information someone could give you over the phone.
