In the end, the only way I managed to get my original account unlocked again was by collecting a huge list of @amazon.com support addresses and writing a bot to spam hundreds of emails until someone competent picked up and realised my account had been mistakenly locked. I made dozens of calls but they hung up the phone most of the time (literally).

"Oh, they must have had child porn in their drive."
"I bet they were spamming."
"Return fraud, totally sounds like return fraud."
