First check the order status in your order history.
Status "Awaiting payment"? Cancel it yourself by clicking "Cancel order" on the details page.
Status "Payment accepted"? Call us at +1 (828) 415-3679 so we can cancel before it ships. Our support team is based in Europe. You can reach us Monday to Thursday 8:00-17:00, Friday 8:00-16:00 CET (2:00-11:00 AM / 2:00-10:00 AM Eastern Time).
Status "Preparing order" or "Shipped"? Too late to cancel. You can refuse the package at the door. Once it's returned to us, we'll arrange a refund or gift card with 10% extra value.
