I recently received a report to Amazon of copyright infringement from someone who I firmly believe has no rights to the copyright. I think this is a fake report or trying to knock me down. I contacted the person who reported me and only received unacceptable attitudes and words from them, they are an uncultured person. I tried to file a DMCA Counter-Notice but was denied by Amazon and asked for an authorization letter from the owner. I have researched and searched carefully and this digital product is not copyrighted. Is there any way I can file a DMCA Counter-Notice at Amazon.ca?
