I sold a digital download key for Metal Gear Solid V through eBay. This was a redeemable game through the nVidia promotion. This was sold on 22nd September, paid for through paypal and today I've received an e-mail from Paypal the buyer (whom I have e-mail and full address) has now reversed the payment and raised a dispute.
I don't believe I've broken eBay's terms looking at their website, digital sales are permitted and my instructions to download the game were sent within 1 hour of the purchase, via eBay's messaging system so I have proof of this.
It's just a massive pain in the a*** to have to go through all the motions for the sake of £25. From experience am I likely to see my money when all is this is over?
