Ok Alex... won't work since all these calls are phantom display numbers. This means they are not real phone numbers. They can put the call display number to anything thing they want. Reporting to the CRTC is pretty much a dead end unless you know for sure who the company name is, and their number is.
I caught one such company once by actually agreeing to getting my ducts cleaned, and waiting until they showed up to my house. I took the license plate down and told them I didn't order any service what so ever. Then I reported the license to the CRTC... Again that lead to nothing. The CRTC won't even investigate something that was a sure thing.
What I keep doing now is agreeing to their service, but they got clever and asked for payment up front now. I just keep telling them I don't give my credit card over the phone. Eventually one will agree to come out and so call clean before they get paid, and the next time I'll report to the police.

Just report them to CRTC. Google them and lodge your complaint.

(416) 222-2333 has called several times through the last week.
On Friday Oct 15 they phoned twice. 1st call at 5:30 pm, no one on line when I answered. I repeat hello, still dead air. Then about 5 or 10 seconds later a recorded female voice stated "we're sorry" and the call hung up. 2nd call at 8:40 pm. Again no one on line when I answered. Dead air for 20 seconds followed by a recorded female voice "good-bye" and call hung up.
On Sat Oct 16 they phoned at 9:20 am. This time there was a male telemarketer ready to try to pitch us. Indian accent and obvious boiler-room atmosphere in background. Standard, annoying fishing tactics: "Is this Mr XXXXX?" repeated twice when I decline say yes or no followed by "How are you doing today?" to try to trick us into converstaion. Always refuse to acknowledge, or deny your name - let them keep guessing, since they obviously using old lists and don't know you. Then he tries to pitch some sort of duct cleaning service, using an unclear company name. I stated that the number they called does not contract over the phone and asked to be put on their internal "do not call" list. Telemarketer agreed, and was generally cordial, but we need to see if calls continue. After all they did call with recorded messages and hang ups at least 3 time prior to events I have described here.

These morons call me everyday, and everyday I say" eat s**t!".  Finally, they called and I had enough.  I said " Sure, I'll book an appt, does that mean then you will stop calling me?"  The indian guy says" Oh yes sir, absolutely!'
I say" How will you do this if it's a computer automated calling machine?"  
He says " All I have to do is click option D and that will stop calling you"

Can you believe this sh--?  Everyday they call, and everyday I say "no and stop calling me!"  They didn't stop calling until i booked an appt and when they came to my door in their heap of sh-- truck i told them to F--- off and stop bothering me.    
Crooked little as$holes leave me alone now.
