About 10 minutes after I left the dealership in my new car Thursday, my cell phone rang. It was a private number."This call is to inform you that the factory warranty on your vehicle is about to expire."It was one of the sometimes-illegal robocalls that are sweeping Kentucky and the nation. The scheme works like this * or* the caller wants you to call and buy a new warranty, when you really donβt need one (something to explain what this thing is all about).The New York Times City Room blog has some information on Sen. Chuck Schumer and the Federal Trade Commission's fight against these calls.The scam apparently generated about $10 million dollars. I suppose that's no surprise given how many calls I was getting. It every day for a while, even though I'm on the do-not-call list.To sign up for the do-not-call registry, go here.
