He's dealing with Amazon, an american company. They won't listen to anything else. Heck, according to the article they've explicitly said they won't listen to anything else since they've told him not to contact their support.
Edit: Turns out the real content of the closure message is available online:
It includes the following line: "If you require additional assistance, or have any concerns, feel free to contact us directly at account-appeals@amazon.com."
This was conveniently left out of the story, and there is also no mention of his appeal made in the article.
He's dealing with Amazon Europe Core SARL, and Amazon EU SARL which are not American companies. Their addresses are both: 5 Rue Plaetis, L-2338, Luxembourg.
Their registered adresses don't matter when their policies are dictated by the american head company. They're not somehow magically free to make 100% their own decisions just because they're in another country.
