No message left, but when I tried calling the number back, I received a vm message that said no one was available.  Assuming this is a telemarketer.

Called. Did not leave message when my voice mail specifically asks you to identify yourself and I will call you back. That is always a spammer when they just hang up. Now blocked.

There's a new kind of scam---they get people to say words, and they are able to mimic your voice with some system, and then they make up that u "agreed" to  buy something for X $s, and then they pressure u to "pay up" or else.  NEVER talk to these snakes so yhey hear your voice (I'm not making this up).

They called but left no message

Hey [***].
It was a recording saying that i had won a trip due to me being selected from leaving my phone number at a resort.  I don't [***] leave my personal phone number.. You dumb [***].
