Car Warrenty company Can you hear me Phone Phishing Scam

They always call and tell me that they have been notified that the extended dealer warrantee on my Cadillac is done. And they want to offer me another warrantee. Usually I say no because I don’t have a Cadillac Yesterday I said "yes" they asked the question again like they didn’t hear me so I said " YES". And then they hung up.I am nervous because they were probably fishing for an affirmative response in my voice.I only said yes because I was going to try and get passed the computer and talk to a human to once again tell them to stop calling me.
