I sold Nintendo $70 eGift card to P3GGY a few days ago.
After less then 24 hours after the sale the buyer had filed the dispute with zero preliminary communications claiming the code was bad.
I submitted the receipt for the card. However, this is what Gameflip support had asked:
"Please provide us evidence that the code was valid before the exchange had taken place and an invoice for it and proof ", Support ticket 666376
Gameflip support should be well aware that Nintendo does not provide such information online, so it’s puzzling they ask for it.
I was able to call Nintendo support at 1-800-255-3700, provided them with the first 8 characters and they confirmed the card had been redeemed with the timestamp just after the card had been sent via Digital vault.
It’s a clear evidence of buyer fraud
Nintendo also has the name, serial number, and the name of the person who used the code - but they won’t give it to me for the confidentially reason.
GameFlip support has that info and they can call Nintendo and verify details I can’t - I urge them to do that
