Hello, I have been waiting 52 days for a package to arrive from China to New York USA. The package still shows as in China. The seller who provided tracking originally told me the package was in the US long ago but due to delays here had not been delivered. Clearly from tracking the package shows as in China. Is there any guidance on when I could receive this package? Thank you.

Seller has only provided fed ex tracking number. So tracking will not show any overseas movement. It will only start showing updates once package clears us customs and fed ex receives package. I have asked seller multiple times for China post tracking number which they keep replying back stating that my tracking number is fed ex tracking number. Is it possible to track package’s shipping from China post with fed ex tracking number? Or how do I go about getting China post tracking number if seller will not provide it?

My package has been shipped from China 6 weeks ago (tracking code: CP412853996CN).
The tracking system says the package is still in Shanghai.
China Post says the package has already arrived in Italy.
Italian Post says that the package has never arrived and that it’s still in China.
China Post gave me a flight number (LH8403-246). I called Lufthansa Cargo but they said that that flight is not showing.
I have absolutely no idea what to do. Please help me tracking my package and provide me informations. ThankYou
