Who called from 2012213014

Just got a call from this number 10 minutes back on my At&t cell phone. Didn't leave a message.

I keep getting call's from this number...when i try to get info about it they hang up ...now i know why it is only a scam....you people need to find a real job..

Keep getting these unwanted calls.  I'm on a do not call list but they continue to call

Called me on my cell.  Left no message.  No intedning to call back.

Got two calls in a row on my Cell.  My carrier is Virgin Mobile.  I answered the first time and a recording said, "This is your second Notice on your Auto Warrenty".  I hung up.  They called back about a minute later and I didn't answer.
Also, this is a brand new Cell Number, and I haven't given it to anyone except my kids.
