According to the track & trace my order was delivered but i did not receive anything.

It may be that your package was delivered but no message was left for you. Please check if your package was not delivered to your neighbors. If not, please contact our customer service. We will then find out where the package has gone. If it is proven that a package has been lost due to our carrier (DPD), CADAC will resend the order.
