Same one I got today. Caller ID identifies the city is Canal Winchester - looking through all the calls I've got that are spam there are a lot from the city
They have evolved. Today's message was asking me to renew my warranty but she never mentioned on what item. I believe it's one that wants you to say "yes" these people have to be stopped. Called my cell so I blocked it.
I've begun answering calls like this, but saying silent instead of saying hello or letting the call go to voicemail. If the caller is a robo, I hang up and block the number. Sometimes the caller just says, "Hello...hello?" Other times, the caller hangs up. I keep a list of the numbers, and if I get a second call from the same number, I block it.
