Calls at least once a day. They almost never leave a message. The one message they did leave was a woman saying "This is harassment" as if she was describing what it was she was doing. Weird.

these people have called me 14 times in the last 2 days

I got a creepily similar call just a moment ago.
They said that same thing about an environmental survey but asked about energy efficiency instead of air quality. "Call Somebody Inc" showed up on my caller id, along with a local phone number. They wanted to know things about the size of our home, gas or electric, if our power bill was average, etc. The young woman on the other end of the line was actually nice, so I was compliant. She also mentioned something about calling me back about a gift. That's what tipped me off to something seeming fishy. But the strange thing here is that I got this call in Birmingham, AL. There's something odd about it all...

They called me once two days ago and three times yesterday. All four times they stayed on the line after getting my answering machine. I could hear someone breathing (not in a creepy fashion, just breathing) and some activity in the background. They hung up after 10 seconds or so each time. Very strange.
