The DNC list is not universally published, and most of the calls are from a dialing machine not an individual. If you receive these calls you have to answer the phone & tell the person you're on the DNC list and that you'll be submitting their number.
My cell phone has a feature that blocks all calls NOT in my contact list. If it is a legit caller they can leave a message. The SCUM bags don't leave a message. We need to stop this type of calls.
Was a robo call for a pain medication. Called back in hopes that it would have a remove number from call list but it comes back as a non working phone number.
