Got a call from "Ryan" from the "GRA."  He was about to tell me what the GRA was, but the line cut out.

Several calls from this number. No messages left. Hung up the one time I picked up.

Called me. Did not pick up. Left no message!

Multiple calls each day this week. No messages.

Got a call from this number at 07:59 PM (03/28/2014); rang three times (we don't answer unknown calls) and Caller id Showed California Call & the number.  The so-called "California Calls" have doubled in the last few weeks; I'm wondering whether it is the same scammer using several spoofed numbers.  This was a new one for me.  Is now blocked.
