"Matt calling from the warranty department about....."   I interrupted him before he got started.  He tried to repeat his pitch and I interrupted him again.  He ended the call.  Number blocked.  For robocalls I just end the call.  Whenever I get a call from a live person, totally de-railing them before they get started with their sales pitch seems to work. They get frustrated and end the call.

Keep receiving bs calls from folks trying to sell me an extended warranty on a vehicle I have never ever owned. How do we stop this malarkey from wasting our time? I am soon going to have more blocked numbers on this damned phone that valid ones!

This number has called me three times in one day, never leaving a message
