AliExpress complaint: Order ID: 8153827136091740

placed order for smart order on 19th August (Order 8153827136091740) for US $16.06 including door to door shipping. and the supplier sent me the tracking number was CPCN00383504LK. but the express company number never reachable until I got call on 9th Oct to come and collect the package to the nearby town by my own.
I went to the town to collect the package and the time it was handed to me, it looked it was already opened several times, so I opened the package in front of the delivery boy. and the wrist watch box was there but there was no smart watch inside and empty box is there. so I took pic of delivery boy’s motocyle, package inside, package outside and empty box and handed over the box as the delivery boy said there is no documents to sign or any official documents to provide for this delivery.
so you can see from the tracking this was never delivered. I complained to buyer, filed dispute on ALiexpress but they closed the order and seller no longer communicating. I re- appeal but the case is closed. and order is also close. but Ali express cannot close the order since the delivery has not taken place as the package I didnt take. an order cannot close until the delivery is complete. it should either returned back to the seller, or reached the customer. they want me to contact the local delivery company and ask for refund which is not working! I paid for the ALiexpress so I do not want to find who sent me the package as the express company never answer me and they are the dealing with the express companies. so I want to file a case against Ali express because they close the order without checking the delivery status, there is no buyer protection ! please help me with this regard.
