A user bought me an amazon giftcard with automatic delivery, He have 2 days to complete confirm the transaction and pay me, but he open a sell with the same characteristics (including the same descriptiont!).
-This is legal?
-He already saw the code? and if yes, he can cancel the transaction?
Thanks.
This is legal?
Yes if he’s re-selling it unused, but it is suspicious.
He already saw the code? and if yes, he can cancel the transaction?
He saw the code because it’s automatic delivery. He cannot cancel the transaction but he can dispute it (saying it doesn’t work). If he doesn’t dispute then it will auto-complete and you’ll receive the money.
You should post that user’s resell listing and your Order ID in case a moderator wants to see.
Hello! Please, send me your invite code and the listing ID you mentioned, so I can check it?
Thanks!
In the dispute, how Gameflip can prevent the user do not claim the code in other account and then says the code is already used?
Portugues, José ?
