When using a debit card, there is a possibility that you will be charged twice in order to confirm the validity of the card.
Once your card is validated, the duplicate settlement will be refunded by your credit card company.
Please note that it may take more than a week to receive your refund. If you are using a Korean debit card, it may take more than 6 months. We apologize for the inconvenience.
Also, note that this effect is put into place by credit card companies, therefore we do not receive the amount of money charged on your card. For more information, please contact your credit card company.
