The Brick stupid store keeps calling about special sales.

Stupid Brick..  how can I get them to stop calling me?

Tell the caller that you are invoking your rights as per The Personal Information Protection and Electronic Documents Act (PIPEDA), specifically those sections pertaining to Access To Personal Information (section 12) under which the caller is obligated to disclose all information they have about the call recipient including, but not limited to, the source provider of that information.

Or just burp and hang up.

High road, low road. It's up to you :)

Over 3 years later and they start calling again. *Blocked*
