I managed to keep them on the phone for 15 minutes until she figured out I was just trying to waste her time, then she hung up on me. I think that is the worst thing you can do to these people.
Called with the information about a car I had purchased a couple years ago. "A courtesy call to let me know my vehicle warranty had expired." I mentioned they were calling a cell phone on the do-not call list, and he reiterated that it was just a courtesy call. When I asked if he was trying to sell me a vehicle warranty and if they were from the vehicle manufacturer, he hung up. Wanted to get the company information to report the call.
Called to sell a warranty for a car I no longer own. I said "I no longer own this vehicle and have told your company..." Click. Before I could even say I'm on the do not call list. This is about the 20th number from this company that I have blocked.
