Hello, I bought a couple of items but for some reason the italian (shitty) mail service hasn't delivered the package and has sent it back to china. The problem is that I don't understand the actual status of the shipment because seems that it has been rejected by the same customs that allowed the export.

I know that but I want to know how much time should I wait before the package gets delivered to the sender. How much time is needed for the domestic transport from Guangzhou Transit Station to the sender? Why there aren't further updates for the domestic transit?
