I would see if i could register a domain for that company and build them an online presence littered with "AMAZON" key words so that search engines drive everyone there. If you cant find their phone number or address you could put Amazons contact info with "To get in touch with us contact Amazon directly and ask for us by name". Maybe even direct link to some of the sellers amazon items so that when people visit they really GET that this is the "right" website.
