Hey tuannguyen,
Unfortunately, the purchases were refunded to the buyer, because the codes that you sold were revoked afterwards from the buyer’s account.
Also, please verify the following link and be aware of the currently allowed non-gaming gift cards: https://gameflip.zendesk.com/hc/en-us/articles/360002439194-Can-I-Sell-Non-Gaming-Gift-Cards-on-Gameflip-
Further violations will result in the suspension of your account.
God speed!
