This is just an opinion without personal experience, but as others indicated you likely have been snagged by a bot; your case seems really clear cut and a review with a human should fix this quickly. The challenge is to get a human on your case. One option would be to give your rep a heads-up that in 24 hours you will ask your state representative (choose one which likes to bitch about Amazon or monopolies) for help. Or media. You like Amazon, blah-blah, but they are killing your livelihood. This has some risk that Amazon will retaliate and kick you out after releasing your money, but unless you seriously misrepresent your case they have way more to lose from publicity than you do. Good luck!
