Very annoying to hear that the packing slip/return form is missing from your order. If you want to return an item and the packing slip is missing, you can print the order confirmation or invoice and add it to the return package. A handwritten note with the order number and your name/address details is also sufficient. The most important thing is that we can see who the return package came from. If we do not know who the return package comes from, we unfortunately cannot process the return.
