A refund may be considered when payment was verified but the supplier confirms that the top-up failed and the supplier balance was refunded.
Completed top-ups are final. Refunds are generally unavailable when a customer enters an incorrect Player ID, server, region, or character information and the product is delivered to that account.
Duplicate payments and overpayments should be reported with the order number and transaction reference. Refund timing depends on the original payment method.
