Who called from 8475928804

Phone rang once, with a caller id of "Elec Authority"

Phone rang four times and went to the answering machine, but no message was left.

7-03-2014 Caller ID said Roselle, IL.  Didn't answer it, went to answering machine, left no message.

Called but left no message. Caller id said Elec Authority.  If I pick up it starts a recorded message about electric service and how I can save money. I always hang up.  I believe they call using other numbers as well.

Telemarketing related to Electric Service.... don't know whom to trust anymore.
