"survey call for lake apopka natural gas. we might call back later"

I received a phone call asking if I wanted to be on a list made up by the FCC.  It was pertaining to the FCC asking residents if they wanted ads sent to their cell phones.  They asked my age range as well.  I said yes without thinking as I was doing something at the time the phone rang.  Now I'm not so sure I'd want to be on any Gov. list.  I'm on a DO NOT CALL list.  Anyone know what this is about?
