Who called from 5807130967

I keep hanging up when I answer, they have called twice within a couple hrs. Annoying.

I have recieved several calls from this number, 580-713-0967, on my answering machine.  No message is ever left. Reverse lookup says the number is in Lawton, Ok. very annoying

5 calls from 580-713-0967 in 4 days. No voice mail left. Sometimes only rings 3 or 4 times.

Caller says it is a political survey.

Just called.  They always hang up before I can answer it.  Very annoying.
