I've received these calls every so often in the past couple of months. I never answer the phone anyway, so they can waste their own time looking for survey data!
Yea they just called me and I didn't answer. For those who don't recognize the 604 area code, it is the Lower Mainland (Vancouver). Looks like Aug 2010 is phone call month.. This site is great btw. I have found so many numbers on it.
