Do not know this caller. IT was obviously computer-dialed, with the typical delay before anyone speaks. Just before I hung up, I could hear background noise (ie. as in a call center) and a woman with a heavy accent saying "hello".
Same deal as other 2 posters. I don't know if these people are in Marin county CA, but I live in San Rafael, and the number is listed to someone in Ignacio, CA. Same county.
I have received numerous calls from this number as well. I'm also in Marin Co. Number is definately an Ignacio number but "disconnected". Each time I get a call I go onto the Do Not Call registry and file a complaint. Hope someday this will stop.
