I've mistakenly marked my order as Delivered. What should I do?

If you selected Yes on the confirmation popup at the top of the page in the order details asking Have you received this order?, the order will be marked as Delivered.

If you did it accidentally, not having received the product, that's okay. The fact that you marked it as Delivered will not affect the shipping process. The only thing to be concerned about is that you won't receive any non-delivery warranty reminders. In this case, we advise you to keep track of that warranty yourself. We described the process in What is a Delivery guarantee?
