I answered. Automated robo dialer informing me that my vehicle warranty has expired and they have sent the final courtesy reminder. This was my last chance to reinstate my vehicle warranty. When asked if I wanted more info, I answered 'no' a few days ago, but today answered 'yes' and they still hung up on me.
Caller left no message. Called back this number twice but got phone company recording of "your call did not go through" so I assume it's another of those million junk spam callers. Silly me for thinking it might be someone I actually know.
