If you are on the Do-Not-Call list, make a formal complaint. I contacted these scum from a number that they couldn't return a call to me and asked them for company information. They supplied the information and I looked them up. They have several BBB complaints against them, but it would be nice if several of us report them for illegal calls.

Received a call. Hung up when I answered. I called them back. Caller ID: 2396763730
then phone number 239-676-3730. They said they were a "Warranty Service for your cars".
I get this number calling every single day including weekends, and sometimes twice a day. They hang up after the third ring so it never gets to voice mail. My phone ID tries to announce the caller 'NPS' and unfortunately it sounds similar to a family member's name, so I stop what I am doing to check. Annoying!
