Who called from 7609335570

Called twice and left no message.  Called back and just got on-hold music. . . Blocking.

appears to be threatening calls with growing frequency - i am afraid.

No message.

Began upon receipt of new phone number, after moving.  This month, 28 calls in 6 days on blocked call log.  Rapid redial autodialer.  This has been going on for months, totaling hundreds of calls blocked.  No messages.  Insane.

My CID said "Hammil CA" which is a tiny town located just N from Bishop CA.
