The recourse for anyone else would be a lawsuit in small claims court. That would at least get their attention, and possibly an issue resolution.

Credit card chargebacks for every kindle book you bought? Would probably remove all chance of reconciliation, but it would send a message.

I doubt it works just like that. If you do that you'll have to file for a claim, which will then be investigated by your bank or credit issuer. There's some procedures around what you can and cannot claim for and more things that need to happen according to the Fair Credit Billing Act (in the US). Since you've already taken possession of the good and used it I'm not sure you'll get much out of it though I have no idea how this would even work/apply to digital works.

And I doubt they'll let you go back years.

Your credit card company needs Amazon more than they need you. They would side with Amazon.
