How do I contest negative feedback?

Question

I made a sale and thanks to me and the buyer I realized that I had actually produced, in fact I tried to make up for it by saying that the buyer no longer wanted the product and it went well as I wanted, the buyer did me a favor, the buyer left me feedback that is not right for me, I have never had any intention of scamming on eBay besides, when we spoke on the phone he was maddeningly drunk

What should I say, since the seller is me, I said what happened, pure truth, I hadn't noticed the mistake in the sale but I fixed it right away

Are you sure it was the drunk buyer? Good evening.
