In the US, you want to send mail to the registered agent. That's the person on file with wherever they incorporated who accepts legal paperwork during business hours -- and thus can always easily be reached by mail. Companies are required to have one of these, and they'll deal with routing legal complaints internally. Just send your angry letter with tracking to the registered agent, so you get a signature when they drop it off. For Netflix, it seems like: > The address of the registered office of this corporation in the State of Delaware is Corporation Trust Center, 1209 Orange Street, City of Wilmington, County of New Castle, Delaware 19081. The name of its registered agent at such address is The Corporation Trust Company. So if you send your angry mail there, Netflix legal will almost certainly read it.
