Why is it so hard to speak with a local USAF recruiter?

I'm a navy vet from the 80's and my grandson wants to join the AF after he graduates HS in a few months. Both he and I have been frustrated by the difficulty to actually connect with an AF enlisted recruiter nearby. We're in San Diego CA and virtually every number we call is either out of service or has a generic voicemail drop that is not convincing. We went to a local AF recruiting office and it was locked and no one answered phone or the door speaker system. The USN recruiter next door did not even know if the AF people were in or not, just gave us a business card that my grandson already had from his school and which did not have a valid, working number on it. Web links are similarly useless, either giving out of service numbers or ones that no one answers. Gotta say it was a disappointing experience!
