Have you just placed an order but changed your mind? Then cancel the order with the webshop where you placed it. They will forward the cancellation to Billink. If the order has already been shipped, you can refuse it at the door. If you explicitly indicate this to the delivery person, they will return the shipment. If you've already accepted the shipment, you must take care of the return yourself. Consult the webshop in question for this.
