Thursday 28 April 2016 -- 3:23 pm -- Called my cell phone. Caller ID said "Corona CA". No message was left. Google search reveals no comments on this number, but one "reverse white pages" site flags this caller "suspected spam".
6/19/16 9:28 PDT Tried to call just now and since number not recognized and ID is SERVICE, did not answer and, of course, no message left. Based on what I have read here, will now block this number along all of the others who try to get answer with a spurious ID.
