It sadly sounds to me like Amazon have closed the internal case as suspected fraud. From that standpoint, I can (very cynically) see the reviewing agent looking at potential photos of the shipping label on the box and thinking "oh the person finally figured out what format we use and printed a label" or "oh they found a random box they're claiming as theirs" or something like that - ie, innocent until proven guilty because of the fraud flag, and the agent needs to meet their quota and their 30 second read of the situation is never going to warrant escalation, much less reversal. (Assuming Amazon industrial-scale micromanagement, I'm guessing there are penalties for escalations that don't prove to have been worth it - and this probably looks like one of those.) I'm completely with you in terms of the cost being potentially ruinously significant. Yep, this is definitely a broken situation. At the end of the day, I think the canonical solution with situations like this is to go viral on social media, as awkward as that is. Network effects and virality are unpredictable and it sometimes takes a while for things to take off, but if you've still got some mental energy left and motivation to seek closure, the data you've collected presents what appears to be a very open-and-shut case which will help to elicit a "wat, what gives" type response, and the relative cognitive simplicity/neatness of the case would very likely encourage knee-jerk sharing. I guess it would just be a question of figuring out how to summarize everything and where to put it - here? FB? Twitter? etc.
