Received call from this number. No message was left. I called back and an automated message said it was some kind of survey that had already ended. Also, if I wanted my number removed from their list, press 9. I did. Will see.
never press a key that someone tell you too, recording or not, this can transfer you to an overseas calls that you'll most likely have to pay for .Also it tells them a have a live number, and you could get many more calls. My opinion, play it safe and hang up.
