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.

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

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.

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.

Said he was from Sterling Solutions asked about air quality and proceeded to asked if anyone smoked in the house if anyone had asthma. He asked how long living in house and asked if anyone what type of work we worked in and if we worked fulltime and how long.Can't remember name. Said might win prize and confirm number he had called me at. Just seem to ask more questions were asked off topic of air quality. My guess is vaccum sales and checking if we can afford the overpriced Sh_t.
