Received a call from this number but I didn't answer. Unrecognized. No message left.

Answered call.  Automated survey calling themselves Green Energy Resource Group.  Says you won a free  2 person cruise to the bahamas.  Will ask three questions about renewable energy and then ask if they can give your number to a cruise line.  I answered the questions and said no to the cruise.  The automated caller then apologizes and hangs-up.
