1. How can I make it stop? You signed up for the Do Not Call Registry ages ago, but you’re suddenly getting a bunch of unwanted calls. What can you do? Hang up. When you get illegal sales calls or robocalls, don’t interact in any way. Don’t press buttons to be taken off the call list or to talk to a live person. That just leads to more calls. Instead, hang up and file a complaint at donotcall.gov.
