A to Z totally bs. How can you appeal this?

I had more than 30 atoz last yr and all won, but not this time. Can you help how i would appeal this case?

The dude bought the item. I shipped and delivered on time (bought shipping label from Amazon).

The buyer contacted us to say that the item is not as described and asked for a refund or replacement.

I asked for a photo of the item.

The buyer said that they threw it away already. Still ask for a refund or replacement.

I said no until I received proof of the item not being as described or return it.

Then A-to-Z showed up.

I described it as above and lost the case.
