The caller identified himself as "Craig" and asked for the person who handles the 3rd party phone lines. He refused to state the company name or the nature of the call and has called back repeatedly since without leaving any messages.
This is a "we can place you on the front page of google" they drop the call the second they realize you will not play ball with them.
when you call the number back you get a "recorded message" of the guy who is trying to pretend he is the phone company but is actually just him trying to get you to hang up.
THIS IS A SCAM if it was real they would not not go to these lenghts to hide.
