I just got a call from this number on my work phone. Since it's my work number, I have to answer it, in case it's actually about work! (lol). Anyway, as soon as I heard it was about my auto warranty, I hung up. I guess they don't know that my warranty expired years ago. My car is almost 17 years old. I don't know if this is technically a telemarketer, or spam. Can they be both?
When I get calls on my cell from numbers I don't recognize, or aren't programmed into my phone, then I don't answer. But on my work phone, I don't know if it's someone calling about an account I'm working on, or what. Total waste of my time, these calls.
By the way - if you call them back they now know they have a "live" number. Even though you can "block" your number easily, they can now sell your number as a verified number, with higher value to other telemarketers.
