DNC lists or what have you, the most effective way to stop these calls is to inform the caller you no longer own that vehicle and hang up on them.

Tried to sell me extended auto coverage. I said, oh my, that vehicle was in a horrific accident. The driver lost control, went up on to the sidewalk and ran into a telephone booth and critically injured the telemarketer inside. This guy stayed on the phone throughout the whole call before he hung up.

I didn't answer.  They didn't leave a message.

Same as others. These idiots tell me they are with National Warranty Service and the warranty is expired on my 2013 Buick. I just yelled at the guy and told him I do not own a Buick; they call every day and I'm sick of it, so STOP calling me. He hung up with no comment at all. Jerk. They call several times a week.  I usually let it go to answering machine just to see who it is. Sometimes it is a woman saying "Hello? Hello?" When she calls, you can hear background noise as if she's calling from home with children and TV in the background.

Call automatically blocked as a robo caller. Caller ID said "Frisco".
