If your parcel already shows severe external damage on arrival, so that it is very likely that the goods inside are also damaged, you should refuse to accept it immediately. Furthermore, make the parcel carrier aware of the damage and note it in writing.
If you have accepted a damaged parcel, please take pictures of the packaging before opening it. If the goods inside are actually damaged, contact us and send the pictures directly by e-mail to bestellung@die-form.de.
Then send us the damaged goods by return, using the returns label from your order confirmation.
