After several "hello?" 's from me, a computer robo-dialer said, "Goodbye". This is about the 100th call I've had regarding my Kia. I'll never buy another one since they obviously sold my information to scammers. This is how they get around the national do not call list. If you've done business with them, they can call you.
Just got a call from 970-236-2179, extended warranty. Said "hello" to trigger the recording, then put the phone on mute. Got one more recording (in a different voice) that said "I didn't understand your response..." then tied up the line for five minutes total...
