Yet another in a long list of companies telemarketing illegally. I didn't answer, *67 to return the call without caller ID and got a recording: Thanks for calling, the survey has ended. Probably just fishing to find live numbers.
They are scammers. They called a number on the Do No Call list, I didn't answer. I blocked my number and returned the call to get a message saying that the survey I was called for has ended. I've gotten no less than 50 of the same type of call from different numbers - pretending to be a survey to get around calling numbers on the DNC list.
That in itself is an indication that they're disreputable and likely scammers. Other sites indicate they're offering vacation packages.
