the FBI's Internet Crime Complaint Center (IC3)

Don't be cynical... it might produce a result.

Save all your correspondence with them!
They have violated the terms of a published contract and contravened many international laws.
I have saved screenshots of everything from their website and urge everyone to do the same.
