Who called from 3126516170

I just received a call from this number 10/19/12, no message and I don't know who this is either.

Received a call, no message.Found this about it on a similar site: I have had several calls from these people to my home number which is on my do not call list, and have pressed 9 to ask them to take me off their call list.  They are very rude when I don't want to talk about their agenda and hang up on me.  Then I get the calls again.
