Wrong Tracking Number Provideo to the Customer.

I bought sunglasses from the shop called MEYOU around July/August 2017 through Aliexpress. After receiving the email that the parcel has arrived in my country, I went to my nearest office to get the parcel, the post office tellers tried to track the parcel only to find out that the tracking number that Aliexpress/seller provided to me is incorrect. I tried so many times to explain to the seller what is happening. The seller keept on telling me that """hello dear order amount less than 5 dollors ，all choose China Post Ordinary Small Packet Plus，not register and abroad information hope you understand thank you""" Or to check my parcel to the nearest post office. Even if I have explained my tracking number issue to the seller. The I decided to ask customer care to intervene but still no assistance they keep telling me open disput yethe they already closed the order without me confirming or leave feedback. And now I need my refund back or they must resend the parcel with the correct tracking number coz I paid for the parcel. I need fair service since it is not my fault. I thinknow Aliexpress now they are having ***** as sellers so please check before they do this to other customers coz it hurts and frustrating.
