A woman called me from the number.  She asked me about a person named "Zhou Ni" and wanted me to take a message.  I told her "Never heard the person before.  She did not tell me the reason she called and hang up on me.

I just got the same thing! I didn't call back though. same person, same number. Was she foreign? Some kind of accent. Scam?

Apparently this is Schrieber law firm.  When I called, the person who answered, Monica, was exceedingly rude and try to get information on a relative.  Refused to tell me why.
