Received a call from (519) 686-9381 on March 14, 2009 before noon. Caller was asking about the air quality in my home, I said it was fine now that I have an air cleaner. Caller asked what type of business I was in, if I owned the home & then asked if I had a spouse. After I hung up I thought it sounded strange so I *69nd. All I could find out is that it is a Bell land line from London ON. Was this on the level? Thank you.
