Someone called to talk to me about a factory warranty running out on my vehicle from this phone number. They knew what type of vehicle I own, and when they asked me how many miles I have on it, I said I don't want to talk to you and I hung up on them. Why should I give out my info when someone cold calls me?
And you shouldn't!
Do report them!
