I've been having the same issue, getting calls from them every day which I do not answer.
If you call them back, press 1 for service in English, and then press 1 again to be added to the do not call list, you enter your number and should be good to go!

This number has been calling my cell phone 1-2 times a day for at least 3 weeks.  How do I make them stop??

filed a crtc complaint at https://www.lnnte-dncl.gc.ca/index-engIf everyone did this eventually the govt would get off their butts and outlaw telemarketing completely by giving big fines to the phone companies that are making massive profits on these calls.

Calls frequently, days and evenings. I have never answered. Caller never leaves a message, just hangs up. Persistent.

received a call from (514) 847-3629 on March 6/09 -

Called several times and didn't leave message. So annoying.
