They just don't stop calling me last days, but I don't answer when I see a phone number I don't know. No messages left. But I'm wondering how did they get my number, because it supposed to be confidential.

Thanks for the comments here to determine who this is...If you don't have the courtesy to leave a message when calling at dinner time - Don't bother calling again - Thanks Shaw for the call blocking feature!

Who is this person, company?

Dead air, called the number back and learned it was the Conservative Party of Canada.

I just got a dead air call from them at 2:30pm 5 November 2007
