They know that you didn't participate in any survey. That's just their way of sneaking under the DNC Registry wire because you can't proove that you didn't take a survey. These Toads will stoop to any level..
Called my cell phone (which is registered on Do Not Call). I didn't answer and they didn't leave a message. Hate these calls! So sick and tired of them and being on Do Not Call List doesn't seem to make any difference at all!
