Escalate It now.

Their assessment will also be based on the evidence that you've requested.

I’ll do just that now.

Whether they can retrieve It or not, Is not your problem.

You want your Item back, and that's the end of It. In terms of the claim, they've disposed of the wrong Item you've (seemingly) received, so tossing It In the trash works against them.

The only problem with this, is that it does state this in their t&cs about ‘mistaken’ returns:

“ Please ensure you enclose the correct and complete item when making a return. The correct item must be returned to receive a refund.

If you have accidentally sent the wrong item to Amazon, please contact Customer Service as soon as possible as Amazon does not store mistakenly sent items. Amazon cannot guarantee your item will be found and returned, and no compensation is provided for incorrect items sent to Amazon.”

I’m going to spin a story about how I didn’t know it was a ‘mistaken’ return, so even if it wasn’t the item that I ordered, it wasn’t a mistaken return. Otherwise, they could simply refer to their policy.
