Got a call from this number 5:20pm today. Did not recognize number, did not answer and let it go to the answering machine. They hung up before my outgoing message finished, which usually indicates a human at the other end rather than a robocall. CallerID said CALIFORNIA, which I have only ever seen on bogus calls of different types. Called the number back, and got telco recorded message "LA Zero 2 - Message 3 - the mobile number that you have reached is either disconnected or no longer in service" meaning it is highly likely that the number/CallerID is spoofed.
So I made the mistake of answering a "PRIVATE CALLER" Caller ID yesterday and got some dude selling energy something or other. I just hung up. Well today, my phone is ringing off the hook with these scumbags - 'Got a live one fellas!' Anything that says "CALIFORNIA" or a city name is likely A FAKE / SPOOFED NUMBER... so DON'T ANSWER THE PHONE! Please folks - tell your elderly grandparents or parents - these are the ones these telemarketing freaks are targeting.
Now I'm gonna have to tell my sis to *82 before she calls to unblock the phone (i.e. no more "Private Callers) or I'm not answering.
