There is no tracking information for it at present. Possible reason is the seller just gave you a tracking number but hasn't shipped it. You'd better contact the seller to confirm for the reason.
Hello, I shipped a pack CP068222782IT in December 2020, arrived China the 4th of January, then it stocked at custom, last news I had from tracking pack service showed it on the way back to Italy at Shanghai the 15th of March, then nothing more.
The pack contain my thesis.
from 4 Jan till March I had no news of it, and now I don't know where it is. Can you help me about? last track showed it the 15th March in Shanghai.
