Who called from 9284334049

I got a call, no message left.

Recorded message saying that my online entry won a free Carnival cruise.

I didn't enter any cruise contest, so I hung up before the message ended.

No name on caller ID.

I got a call from this number, and it said it was from Flagstaff, AZ. They did not leave a message though. Would like to figure out who and why they were calling.

I have a missed call from this number today.

I received a phone call to my cell phone from this number on 10/23/14.  They did not leave a message.  I did not call them back and will not do so because I have no idea who they are.  My cell phone is on the Do Not Call List.
