Yes - as long as your transaction is still in the Trade Protection hold and your payout hasn't been processed yet, you can change your payment method or update your payment details.
Simply contact us via live chat and provide the correct payment information. One of our support agents will update your payment details in the system, and your payout will be sent using the new method once the Trade Protection period ends.
If your payout has already been processed and successfully sent, it is no longer possible to change the payment method or payment details.
