It may happen that your return does not arrive at the webshop. This is annoying, both for you and for the webshop. In such a case, it is up to the sender (you at that time) to inform the parcel sender in question to complain. It is necessary that you have a track & trace code for your return shipment. If your complaint is justified and the package is indeed missing during the delivery process through no fault of your own, the parcel sender will reimburse your costs.
