annoyance call

Picked up call. It was automated... said my vehicles warranty will be expiring. This is the last notice. Would I like to speak to a warranty specialist about extending my warranty?  I said Yes. Transferred and a guy picked up saying "Hello?". I was vague with my answers and was told they'd sent me a final notice about my warranty. So I asked which vehicle. He said he "didn't see a vehicle on my account, so it was probably my primary vehicle.". I questioned the fact that he was calling about a car that he has no information on and he then told me that he was ending the call (and hung up). Obviously a crank call; probably fishing for people to give out information or even pay money.

Called my mobile number.  I didn't recognize it so I sent it to voicemail.  They left no voicemail.  Due to Bueller's comment above I added them to my block list.

Thanks for taking to the time to post about this. Very informative.
