Scam Dispute?

Description

So I got scammed for a video game account on eBay, the seller asked me if everything was alright about an hour after purchase and I said yes, after that the email password was changed and I was locked out of the account, I lost the dispute on eBay because they don’t allow refunds on digital items, the scammer is using that as his evidence, and he is calling me a scammer, is there any way I can upload documents to the dispute to prove my innocence?
