Didn't answer, since I've learned it doesn't help, but actually tells them the number is a real working number.  Caller ID said "JAZZPLAYER"

Received a call from Jazzplayer as well (approximately 1pm EST on Friday, 10/12/12). It was a credit card rate reduction recording. I'm SO FREAKIN' TIRED OF THESE CALLS! (Our home number has been updated on the Do Not Call registry every year and we STILL get these damn calls.)

First it was Rachel from card services @ 12:53 and now @ 1:40 its a free trip to disney world. I can put a block on the number but I'm sure next week they will have a new number. Just filed a complaint with the National Registry for whatever that's worth.

got a call from this number. didnt answer.

This number just called my but didn't leave message. I see now it's just another scam call to block. Los Angeles, CA.
