called me at 456 hst

Called at 4:23p.m. HST no one on the other end of the line.

Has called me SEVERAL times in the past 2 weeks but I don't answer and they never left a message until today.  It sounded like some automated robot clicking away in the background but didn't say anything.  Read somewhere else that it may be Special Olympics.

I have gotten 2 calls from this number and my Caller ID captured the name. When I called them I got an automated message. They are a fund raiser for charities.
