I got my new cell phone on sunday and in the next 48 hours got 4 of these "caller unknown" calls from 323-372-5902. I didn't answer any of the calls because I hadn't even given out my new number when the calls started coming - instead I googled the number and found this page.
This number constantly calls me and wastes my pay as you go minutes on my cell phone. When I answer it a recording says something like "if you want to leave a message..." When I call the number back a recording states "You are not a WCA member...." I wish there was a way to block numbers on my cell phone.
I i gps'ed this # & git its exact location. I don't kmow the area nor anyone who lives there. White pages app for android is an extremely useful tool. This is a harassing caller.
