Calls almost daily. Never leaves a message.

This number has called with caller id Neilsen
Several times a day for the past week
They are also calling after 9pm which I understand to be illegal
How do I report them and to whom do I report them to besides the do not call list

[***] you. Last time to come to this site.

Uh... These are the TV/radio ratings people. 100% legit company. (Source: Myself, not affiliated with them. And their mail. Open something from them and you'll find money enclosed.) If you pick up this number, you could take part in the ratings for a week and will make money just for getting a booklet.

...there is a ONE DOLLAR BILL in the mailing.  I never participate - I don't watch TV or listen to the radio regularly.
