Usually, once payment has been made, it can't be refunded. If you have not received everything you have paid for, please get in touch with our support team who can help you get your items. (see FAQ: My Payment didn't arrive/arrived partially)
If you wish to request a refund, please contact our customer service and provide relevant proof such as an order screenshot.
If there is an abnormal amount of refunds associated with your game, you may receive in-game warnings and potentially face a ban from our game.
