I read your comment before reading the post and you gave me the wrong impression of what happened. He did not "call the tech support line for a copyright infringement". He contacted the company to ask for the proper contact information to deal with this problem. This is not unreasonable - he did not demand the tech support to address this problem, he just asked for the right venue to do so. After that, he was talking with corporate, who did not respond to him. I'm sure hiring a lawyer and sending a proper letter would give him better results, but if you trying to solve something amicably, emailing through the official channel is very reasonable.
