Your refund will still go back onto the card details used on your order as long as the card account is still open.
When a refund is processed, the money is sent to the account linked to the payment card, not the card itself. This means if you've got a new card, as long as the account the original card was linked to is still open the refund will reach you with no issue.
When a card is lost, stolen or cancelled, we can still refund the account. We cannot refund your order to a different card.
