Who called from 8603147297

Just got a call from (860)314-7297.  My cellphone's Caller ID shows call is from Bristol CT.  I answered "hi" and heard my own voice echoed.  No one responded and then I got disconnected.  Never smoked, and never given my cellphone number to anyone I do not know.

I just receive a phone call from that number, don't pick up.

American Customer Care calling about our internet and telecommunications. They hung up when I put them on hold.

called again to day and will not leave message. Searched the weband found main office and called them. Very nice lady is putting us on their do not call list.
