Just another worthless scammer.
"Hello this is Lisa with the Green Study Survey Company and you have won a free cruise to the Bahamas..."
I usually turn the phone on, then off, and then block all calls with just a city/state in the caller ID, at least when I'm home. When I hit the on button a recording started immediately before I could hit the off button. Anyway, it's just another scammer as all such calls are.
