Some sort of automated (survey?), I dropped the call and added it to the DO NOT ANSWER list. They can call back, but I won't get any bothersome calls again.
Most of this kind of useless 'survey' ends with YOU HAVE WON A PRIZE! or some similar sales trick, and the 'survey' is purely so that they can get around the DONOTCALL.GOV restrictions. Why would anyone do business with a scammer?
