Good point Scarff - In Canada we have a national do not call registry, and if you are registered and have no direct business relationship with them, they can be fined - BIG TIME if they make unsolicited calls. So, to my fellow Canadians, I suggest you register for do not call. If you are already registered and they call, tie them up as long as possible, do not give them any info, and then lodge a complaint with the CRTC when you hang up.
I just love screwing with crooks like these guys.
