Answered call said "hello" 3 times, no one said anything.....called this morning around 10:20 am.  Called number back around 3:15 pm, and recording said "thanks for calling, the survey you are calling is now finished".  Don't know if legit or not, as I live in Cincy, where area code is from, but I am on a few legitimate paid "market survey/researchers" list to participate in paid studies and surveys.
