Spoke with 'Scott' and asked where they received my number (selling a free home alarm system). Said I was identified a home owner with no alarm. I then asked again who supplied my number to stop these types of calls, he quickly hung up and I can't call back.

A violation of all the laws about the "Do Not Call" list.  And I suspect the "Free Alarm" is fraudulent, too

No message caller ID said free alarm system

For all you lucky folks receiving these calls, maybe this will cheer you up a bit:

From dianamey.com "Mey vs Monitronics International, Inc.; Versatile Marketing Solutions, Inc. d/b/a VMS Alarms; and UTC Fire and Security Americas Corp, Inc. – Class Action pending in US District Court for the Northern District of West Virginia Case 5:11-CV-90."

They have been violating the  DNC for years and yet they seem immune from any action by the FTC.   What gives?
