We can not stop these calls in western N.C. So I play their game. When I received a call about my car warranty, it was expiring :so they said. I ask which car. was it this one, that one and so on for 7 or 8 cars (which we do not have) giving year and model. I pretended to get very up-set and even cry, saying how I had let my husband down by not being on top of everything.This went on for abound 10 minutes. At long last this man ask if he could please take my name off their to call list. Guess what? 2 years and counting no more car warranty robo calls. (The septic system call was even better)
