Got a call right around 3:45 PM (EST) and was claiming to be an insurance company. My Service provider is Comcast Digital Voice. Caller had what I call "India Tech Support" voice and did not use proper English. I called back and got Comcast's "Disconnected or No longer in service" message. Not a voice mail greeting.
It is a land line according to my resources from Comcast Digital Voice. Did the MAN have the "India Tech Support Voice"? If so, than I got the same call too.
