If you had read all the words on the Do Not Call signup pages, you would have learned that the No Call list is limited to "legitimate telemarketers". It specifically exempts charities, political callers, and businesses with which one has done business in the last 18 months.
Also, scammers ignore the list.
The DNC list is NOT a call blocker! If you want to block repeated calls from the above, get a call blocking app, device or service.
Please reply to this post to let us know you read it, and will take steps to resolve the problem yourself.
got a call from this number on my private and unlisted cell. They are obviously just dialing for dollars as I never use that number for any business transactions, and never give it out.
