Under the terms of our "Fan Guarantee" programme you can cancel an order that has been paid up until three days after the order was placed, provided you paid for it with a credit card, or a bank card. You need simply to contact us within three days of ordering to cancel your order. The reimbursement will be done on the credit or debit card you used to pay for the original order.
For all other cases, we can advise you to take a look at the cancellation insurance. You can find all details in the same section.
