Got a call from this # and accidently did a call back. I hung up before anyone could answer. They immediately called me back and left a message, which said, "Hi, D, this is Maria from US Directory. mumble, mumble. Please give us a call." I don't know how they got my number but Maria did know my first name.
I believe its from classifieds.com posting. I posted my business and received calls from this number.
I just blocked it because they've tried calling me the last four days.
