I sent a bunch of stock to amazon, they said one box is too heavy and now half the stock is missing from the 12.

Suddenly they found most of the stock on the link on the shipment it says "stock found" which is great a month ago, but since then it's not been put in my inventory to sell. It's just gone, I've done 12 tickets and they ask me for silly stuff like manufacterer proof. I shouldn't need it if you found my stock. But they close it if i dont provide it.

I'm losing £2000 out of this and it's ruined my business I was just doing well and starting up, now it's gone to hell due to the stock they lost but found. But will not replenish!

Help!
