Just another scammer hiding behind a fake survey. When I blocked my caller id and called the number back, there's a message about the survey being expired...
Just a thought. If you 'phone back, the message on the 'phone is irrelevant. Thy know they have reached a "live" number and can sell that info on to other scammers.
Scratch that previous message. I called the number, but dialed *67 in front of the whole number to hide my number.
The call was from someone doing a survey. Could be a sales gimmick, but the recording said the survey had expired. So, NO don't answer, because then they will know you are a good number to call, and then you might be added to other lists.
