Unfortunately we can't change the order. If the warehouse has not started preparing your parcel, we can cancel the whole order and provide you with a full refund. To cancel it, please contact us here (Order issues >> I want to cancel my order). The moment one of our agents gets your email, we will cancel your order and inform you regarding it.
If it has been already prepared, we cannot cancel the order anymore. Simply reject the parcel when the courier attempts to make the delivery. They will then return the order for free. We will inform you once we receive the returned article(s) and you will receive a refund in due course.
