Who called from 2813979297

I got a call around 5:30 pm.  Answered the phone and after a few second they hang up.

don't know who these ppl. are.  don't want them to call.

The did not leave a message, and I have no clue how they even got my cell phone number.  I tried to call the number back, and I got recording that said either the number had been disconnected or is no longer in service.  Go figure I called the number back within 3 minutes of the time they called me.
