I have called the number for removal 3 times as instructed from one of the posters above.  I have read a ruling from the CRTC website that anytime you request to be removed from a telemarketer list... the telemarketer is suppose to provide a referral number.  I've never been able to get hold of anyone at these telemarketer offices to get one.  The last incident I called the store for whom the ad was for and they wouldn't offer any help.  I think the best thing is just negative publicity for these businesses that resort to this shallow way of advertising.  The ad was for Wet Basement (416) 253-8043.  

CRTC really has to smarten up and start clamping down on this. In the meantime, this is the website on telemarketing from the CRTC. http://www.crtc.gc.ca/eng/INFO_SHT/t1022.htm

I've called at least a dozen times and the voice message keeps telling me my number's been taken off the list... of course it hasn't been.  It's costing me a fortune in ink for my fax machine.

I've also called the number provided to remove my fax number from the list of those being harrassed.  Listed email address for the company, zchost.net, where the faxes are originating from are: promo@zchost.net and mdhost@zchost.net.

If you continue to be harassed, I suggest filing an official complaint with the Better Business Bureau:

...I have chosen to call the company who is employing this marketing firm to ask for a competitors contact information, explicitly citing my preference as a consumer to deal with companies who employ 3rd party companies who adhere to provincial/federal legislation and best practices.

416 253 8043  and 416 201 4209 aka Peerless Mason.

Call them and leave a loooong rambling nonesense message, or just crackle paper into the phone. Fill up his answering service.
