Try the FTC & FCC web sites themselves. You can still file reports there as well besides the DNC list whenever it gets back up.  I don't know if the FTC & FCC are working either though..

 Called 3 times already today   Tired of it  Don't know who it is  Caller ID says Rockford  
Can't report to the Do Not Call List because the Government is shut down  Guess I will just have to shut off my phone    $52.00 a month and can't even use it     Crap on these scammers and telemarketers  Doesn't the telemarketing companies know that people have caller ID and won't answer     BS  thanks for letting me vent
