Customers that steal

I had a customer order one of my products. They took delivery of the product and mounted it on their golf cart. They returned the factory item which my product replaced for a refund. Amazon granted them the refund because they have no checks or balances to see if the return is even the product the customer originally purchased. I was reimbursed by Amazon after doing some leg work like providing pictures of the item returned and the packing slip. My question is, does Amazon do anything to these customers for stealing from the seller?
