Stop calling here!

Tell them to remove you from their call list, in Canada it is law that your information be removed from the caller's list. Unfortunately, lists are frequently sold between marketers so it may take some time for all of the calls to stop. Also, anytime you provide your information for any reason, be it a "free draw" or any other reason, make sure that you add the phrase "no third party marketing". By law, here in Canada your contact information cannot be shared if you add that phrase. This includes ANY time that you are asked for contact information. My wife is very well versed in this subject, having been employed in a parallel industry, has been adamant that I always include that. Even if you don't think it would be shared, add the statement, she had an issue where her information was shared by a company from a warranty claim.
