Caller is trying to sell extended warranties on vehicles.  When I asked her which car she was referring to she told me that she didn't have a list of the vehicles I owned and proceeded to ask me if any of my cars had mileage over 100k.  The caller was actually quite pleasant and professional.  I politely told her I was at work and couldn't talk and that I wasn't interested.   She disconnected the call with a "thank you".  I blocked the number after answering the 3rd call.  The first two I didn't answer and they didn't leave a message.
