Well, I submitted my final eBay appeal. I'm willing to nuke my entire eBay account over this. A guy with 3 transactions is trying to scam me out of $465, and get a free iPhone 14 Pro Max.
So far, eBay has agreed with him even though I have proof of delivery. Apparently he said, I promised him a refund. (I did no such thing)
6 years and over 300 transactions with 100% positive feedback means nothing against a 1-year-old account with 3 generic transactions
