If you google the phone number, an associated website (http://www.buildzoom.com/contractor/u-save-remodeling-inc) reveals its ugly head. They have their license number listed BUT if you lookup the license number on Contractors State License Board, the status is SUSPENDED.  Needless to say, DO NOT answer their calls or do any business with them.

11/18 9:11 PST Just received call but only rang once.  Not sure how blocked but glad it is.  Ever since having work done on home have calls from all sorts of contractors trying to drum up business.  

Caller ID said Han Jino. Identified company as YYB Construction, asked twice if we had any projects in mind. I asked for contractor's license #. The caller replied, "It sounds like you don't have a project, but a complaint." I said I like to know who I'm talking to before answering personal questions. He said, "OK, ma'am," then hung up.

Got a call from someone called Han Jino.  No idea who that is, said his company was YB Construction Inc.  Told him we are not interested in getting any construction work done.   This number can be found at http://www.buildzoom.com/contractor/u-save-remodeling-inc

This is located in the central west area of Los Angeles.
