Just received a call from this telephone number. No message was left. Anonymous callback reached the old thanks for calling the survey has now ended....blah blah blah.
Just got the call, ourselves. Picked up & just listened w/o saying a word; just the dead air of a robocall. From the comments above I'd say they are running at least two different scams at the same time: the 'survey/free cruise' scam and the 'alternative energy' scam. Shows they are not legit in any way; one company would not be offering both these 'options.'
Unfortunately, I've noticed a trend where we get a lot more calls that are within our own state, and sometimes even our own area code, which makes it harder to distinguish the scams from the legit calls, especially since we run a business out of our home. I had a feeling it was a scam when I say the Caller ID, but you just never know.
