Roger is getting phone calls saying that his car warranty is about to expire. Leo says that those Robo Calls are phishing scams designed to get you to buy something. Leo advises putting your phone number on the national DoNotCall list and see if your phone carrier offers a blocked call service to prevent them from calling you back. And if you have an iPhone, you can block the phone caller directly. But it's kinda like playing wackamole because most of them spoof their caller ID or just change the outgoing number.
