Double billing may occur in the following schenarios.
- The card validity check
In order to confirm the validity of the card, a small amount may be debited.
- Transactions with unfixed amount
For businesses such as hotels or rental cars, the transaction amount is not fixed at the time of check-in, so the card may be debited with the estimated amount and then debited again with the fixed amount after the amount is fixed.
- Mail order sales / catalog sales
In mail-order sales, catalog sales, and some Internet transactions, debits may be made at the time of order acceptance and shipment.
- Change in transaction amount
In the event of partial cancellation of an order after it has been accepted, the corrected amount may be debited again.
- Split sales
After an order has been accepted, the amount may be debited again in separate amounts due to delays in shipping of some products.
- System error
Double debit may occur due to processing errors during card transactions.
In either case, if the refund is required, the refund will be made to the balance in the app immediately after the merchant completes the refund process.
Depending on how the merchant processes the refund, it may take up to 60 days (15 days for overseas merchants) for the refund to be completed.
If you are in a hurry to receive your refund, please contact the merchant.
If you have not received your refund after 60 days, please contact us.
