Got a call on my cell didn't answer left no VM! It said it was from Novato CA! Tried calling back from another # nothing but silence never rang then hung up after 43 seconds. So I tried calling from the phone that they called same thing as the other call!! Not blocking this # waiting to see if they call back so I can pick up the phone & either scream or blow a whistle into their ear!!! Then I will block it along with the many other # I have. I swear my blocked #'s are getting to be as long as my contract list!!!
