23 calls in two days from this outfit.

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 .....

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.

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.

Kind of strange - but this number called us 3 times yesterday (answered it the first time and we identified them as a telemarketer, but husband couldn't remember the company's name).  We hung up on them mid-way through.  They called back at least twice after that within a few hours.  Today, they called 2 or 3 times again.
