Call back gets, "Thanks for calling. The survey you were called for is now finished." This is the voice response for the latest in vacation, home repair, and free gift certificate scams. There is no real survey. That's just the way the scammers get around the DNC regulations. A robo survey, that promises you something for free, e.g. gift card, vacation, etc. You'll be asked for a credit card number at the end of the "survey." It's a scam. Block it.
