Hello again.
RS802785382CN is still showing "customs cleared" in China Post tracking like it did on nov. 17. Is there any new information (I know it`s not even in the minimum amount of time if we are talking about delivery to me, but the locked status after 12 days...)
Also, what are the best ways to track this package? I`ve been using the official China Post one on this site and 17track.

Thank you
