Who called from 4088989217

I tried the number.
"The survey you were called for has now finished."

Called 6:27-ish. Did not call back.

Didn't leave voice mail.

called 6:45 pm. No message

The caller left a voice mail on my mobile phone offering a cruise to the Bahamas if I take a survey. Yeah, right. I've had this call many times before--on both my land line and my cell phone--from different (spoofed, I assume) numbers. This has to be a scam because it's too good to be true.
