I got a call from this number but the person wouldn't speak to my machine. The CID said "Wireless Caller". A reverse trace was blocked for a name or business and address. This call originated in the Norwalk, California area. I say area because there were a few general locations that came up, which is a bad sign plus two service providers (Verizon California Inc. and New Cingular Wireless PCS LLC). This all sounds like a scammer caller. No legitimate business would ever hide by blocking their identity and location. Definitely block this number and report it.
