Caller ID Llano, Ca.. Didn't answer, no message.

caller ID said Llano CA
I picked up and robo call said I was eligible for some home gas rebate.   I pressed "5" to be connected to a person but they didn't answer right away so I just hung up.   I know they are bogus because I am up here in Northern CA and I don't  have gas to my home.  Sometimes I pick up if I feel like yelling at someone for calling me with a scam.  I know it won't do any good.

No message. Now blocked
