How do I contact china post to get the USPS tracking. Package came from China with AT386880735CN, however the tracking number gets changed and I dont have it. Package was sent with out a street address. It has my full name, city, state, zip and phone number but didnt have my street address. I was in touch with my local Laguna Niguel postmaster, But package was still returned to sender which I guess is the legistic company that relabels it with new USPS tracking number. How do I correct the package address to include my street as I do not have USPS tracking number. Package returned to sender two days age. PLEASE HELP!!!
