Who called from 3109612003

I just got a call few mins ago. What is the purpose of this scam?

I just got a call from this place regarding a raffle winnings. I knew it was a scam from the get go. Never believe these people.

I did not answer because of the unfamiliar area code.  They left no message.  This call was placed to my cell phone number.

Called this afternoon, left no message. The name display above the phone number on my call display is a crazy bunch of digits.

I called this # back and it said their mail box was full, im wondering what it is full of,  LOL
