I don't think you understand. These people are scamers. They couldn't care less about a do not call list. They don't care if you are on the list, they will call anyway. They don't obey the law. Just block the # and forget it.
Google keeps harrasing me from different numbers everyday and I'm on the do not call list.
I get several calls a day from around the country for the same thing. I cancelled our businesses Google services due to this.
