I actually talked to them.  It's Kids First (http://www.kidsfirst.org/) The site explains a little more what they do...something to do with ratings of kids and family friendly movies. They were just recruiting movie viewers - they will send over 2 movies, and along with that, there are a couple questions to answer.

Has been calling my house, now they Just called my cell phone, when I asked who it was, he told me. Then I asked how they got my number, he hung up.
Charity or not, its rude!

I agree with you. This (202) 747-7355 appeared on my "missed calls" list.
No matter what their case is, I know that my number is on the National Do Not Call List.

Not a sales call. I got to keep 2 movies for free, just had to answer a couple questions about them.

I really appreciated getting a call from a good cause for a change. They were very nice and polite.  Happy to support something positive.
