I would not trust what Thomas just posted about 1-866-246-7196 scam. That number is also listed on as well as scam According to similar comments, the website associated with that number is not registered. Bottom line: the only credible Do Not Call list is the U.S. federal one.

Here to save you the time and effort to stop these calls; call 866-246-7196 scam, give the caller's phone number to verify it's on this do not call request service list, then give the receiving phone number. I waited the processing time and here to spread the word as a quick and easy solution.

The last 19 numbers that have called my house are 3rd parties for ADT, selling security system. I have asked to be removed, said I had a system, only to receive triple the calls (almost as if they're retaliating) so that avenue is useless. I've called the telephone company to block calls....dial *60 when you hear a dial tone and follow the's taken a couple weeks but the calls have greatly minimized.

Calling for security system. I get different calls for this with different number. If you press 1 to get more information. Press 2 to be taken off the list. In the past I've press 2 but still getting calls. So today I press 1 to talk to someone. Right away I tell the person I have a security system. I don't need a one. I've press 2 in the past to be taken off the list. Then the person hangs up on me.
