The next time they call, I suggest you tell them to try (613) 742-4800, which is their head office in Ottawa. See how they like it when that number gets in their "database."

we could always firebomb their vancouver office. they'll probably keep calling, but you can rest easy with the knowledge that you're as much of a pain in the ass to them as they are to you. or start your own wardialer and set it to call their head office whenever you're not home.
