One possibility is that the goods were delayed on the way and not delivered in time. Also, your goods may have been ignored by the courier company. I didn't access the network with you, and your goods may have reached the place where your logistics information stayed and accumulated. Didn't deliver with you. This is the most likely. Contact customer service to have a look.
