Calls but leaves no message.  Probably a scammer.  I blocked the call.

Same here. No answer, no message.

Another sicko who enjoys harassing the public.  They display "Unknown Name" on the callerId display, however the words "Unknown Caller" are not displayed in the history after the disconnect.  They do this to prevent name blocking.  So only choice is number blocking, for which I did.

received a call at 4.30 on 4/12, left no message.

Was asking for my name but when I asked hiw they got my number they hunh up. I called back but the number does apaarently not exist.
