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

Got call for them, doing airquality survey, said i won a prize. I'm betting is vacuum cleaner people, going to show me how their vacuum cleans my air .....

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.

A indian person from this number called and asked if I could answer a few questions, it would only take a minute of my time. I answered the first five or so questions then he asked my what I did for a living as a said I was a Mom the he asked what my husband did for a living. I informed him that i was not married, he then started to drill me about having a child and not being married. I asked if this was a problem for him, he said YES it is a problem. I asked why.. thats when he hung up on me. I tried to call the number back and it was out of service.

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...

Telephone survey, purportedly about air quality, although few questions deal with actual indoor or outdoor air quality issues. Caller identifies self as Ivan, company as Sterling Solutions, doing survey in Edmonton and Calgary areas. Says you may get a call back if you have won a prize for your participation. VERY STRANGE - likely scammers or trying to identify homes they can break into.
