Same here - 3 calls over the last 24 hours! No message - tried calling back and got message saying something like "removed out of conference" & then disconnected. WTF?

ditto here.... no message.

DIDN'T LEAVE A MESSAGE...

Just recieved a call from this number. I called back and the phone message stated the phone number is unavailable.

Caller sounded very vague as if he was reading something from a script and was not sure of what he was calling about.  Very unprofessional and evasive when I turned the table and started asking him questions.  Mumbled something about a free vacation including air fare and timeshare stay.  Scam indeed if you ask me.
