Received a call from 201 537-5973 at 7:20 PM. It seems that intrusive calls are going up, rather than down. No wonder the US government cannot manage resources -- they certainly cannot control their 'DO NOT CALL LISTS'! Beginning to wonder if they can do anything in a competent fashion!
The government does not "control" anything through the Do Not Call Registry: It is simply a list of people who do not wish to receive telemarketing calls. Legitimate businesses honor this list. But... It might surprise you to learn that our society contains certain people we call "criminals". These people do things like snatching purses, picking pockets and robbing banks. Expecting telespammers to honor the Do Not Call Registry is like expecting bank robbers to stop robbing banks because it's against the law. It's naive.
You may also be shocked to learn that the government devotes more resources to catching car thieves and bank robbers than to stopping small-time con artists from phoning you and me. Go figure.
The reason the "small time scammers", and some of them are not so small, operate with impunity is because the government only goes after either big time crooks where they can get showy results, or mostly honest citizens who won't try to hide or resist. Lack of enforcement isn't because they can't, but more along the lines of they don't want to.
