Who called from 2135371400

Somebody calling me from 213-537-1400 all the time and it's ridiculous
I'm realy frustrated

this number called my cell phone! When I answered they never said a word. I would like to know how they got my cell phone no.?

i have received several calls from this number.  They never leave a msg.. If and only if it is a creditor the law should require that they leave a msg. as well as a recorded copy of the call for all records.  Not leaving a msg never lets me determine who the hell it is.

I just got a call from this number on my cell as well.  When I answered they hung up on me.

I forgot to add that I tried calling the number back and all I get is a rapid busy signal.  I'm going to guess it's a call center that blocks incoming calls.  On a side note I have been getting alot of calls on my cell phone lately from places outside of my 602 area code.
