Send us an email with your order number and a picture of your almost-completed puzzle to orders@puzzledly.com. Please make sure that the image is clear enough for us to see which piece(s) need to be replaced.
We will use this information to open a support claim with the manufacturer for your puzzle. They may be able to provide a piece replacement or reimbursement. Missing piece replacement is not guaranteed, but we will do everything we can to help!
