Like their Car Insurance would be as real as the faked caller ID number they call from.
Just talk to them like they are ISIS and calling to recruit Terrorists. And shove an "avocado" up their cornhole.
Same thing... "Sue" the automated voice message, wanted to lower my car insurance rates. I wasn't sure if it was a real person or automated, so I asked what company she was from and then it hung up on me. If I try to call the number back it just disconnects... no tones, no message, nothing!
