Purchases within the European Union are covered by the Distant Sellers Act 2000 and therefore you are entitled to the statutory cooling-off period of 14 business days from the date of purchase to cancel your order for a full refund. This decision must be made in writing to the address provided when ordering, or via email.
Under the Distance Selling Regulations 2000 you have the right to change your mind and cancel an order within seven working days, although some services and goods are not covered by these regulations. If you do decide to cancel, then you should put this in writing, either by letter (a proof of postage certificate or even recorded delivery would be wise) or you can fax or e-mail. A telephone call is not sufficient unless both you and the trader agree otherwise.
