Received call - left no message.

Called, left no message.  I'm blocking them.

Called, didn't leave message.  Tried calling back, got an automatic directory - "Please state your name, and we'll try to direct you."  Didn't say anything, and it rang through...got another automatic response after a few rings, "The Google subscriber is unavailable, please leave a message."  Hung up.

Called back and got same response
