Who called from 2132323224

Called my work phone at 5:35am (PST).  They've made it to the west coast...

Got a phone call at 5 am!!!  Just got to the phone before I could get it, called back and it says "this number is not in use. thank you for calling."  WTF???? how to they get away with this crap.  I want to know how to shut it down. Sounds like everyone has the same problem.

4 times in last hour. beeps.  called back and got message "Number is out of service"

Number has been calling me non stop for last 20 minutes.  It's now 22.30 in London

I'm in Hawaii... Called my tmobile cell phone 4 times in a row!!  Anyone find out what's going on?
