I had a smilar call on Feb 2/12 for a 20 second survey. I said yes just to get rid of them but I am suspicious about them breaking into my house or something like that especially as they asked if I had a spouse. My caller ID shows them to be P. A. Care at (519) 964-0068. I called back later that day but there was no answer.

When I said hello they hung up. Called back and after six rings they picked up and hung up, Called back again and let it ring to hell, over two dozen times before they picked up and hung up. I called them right back - busy signal (519) 964-0072

They call pretending to be doing a survey about asthma, allergies, and air quality.  Then they call the next day claiming you have been selected to win a gift basket and insist upon delivering it when you and your spouse are both home.  I did some research on them - turns out this whole survey and gift basket thing is a ploy to get you to let them in to your house so they can try and sell you their expensive air filtration system.

I just had a call from P.A Care same story as everyone else, wanting to do survey, I wasnt thinking or i would of said no, I figured I would answer the questions since there were only a few. It was on allergies, If i smoked, what my  job was? do I live here alone? any pets? the phone number they used was (519) 964-0072. Once I hung up I got to thinking about It and looked them up online to make sure they were a ligitimate company, I came across many complaints. I hope they dont come and try and break into my house.
Has there been any investigation done on these people, they could be part of a break in scheme? wanting to know If i had any dogs or If i live alone, Im kind of nervous now that I said I was retired and had no dog?

person phoned my home and asked if I was Mrs. Hiscock, when I asked who was calling they hung up.

I used *69 to get their number and phoned 3 or 4 times.  They would lift the receiver and hang up.
