We are on to these guys.  Nice horse head for Christmas.

They call and hang up without any message.

This folks can be annoying. The ID for this number shows up as "UNAVAILABLE", and they don't leave a message. They keep calling until they finally get someone to answer. I answered today when they called (on a Sunday, which is annoying in itself), and the lady said she was from some company, and she immediately asked what county I lived in. I told her that we do not answer questions or take surveys over the phone, and that our number is on the National Do Not Call Register. She said she would flag our number not to be called.

I am getting these calls 4 to 5Xs a day.  They come up on my caller ID, However they never leave a message.  I am registered on the Do Not Call Registry.  I do not know the company. I do have their Number
