I have a couple of packages marked under China post that are claimed to have been delivered yet nothing was delivered. I contacted China post by ermail no reply. I contacted the business by email no reply. It mentioned China post to USPS no record found from my local post office of such tracking number that exist. No one responds: so how do we communicate with China post to confirm or to investigate? Here are the two tracking numbers: AG679502983CN & AG679210367CN it says it was delivered sucessfully? Where, When, to Whom?

Tracking #: AS016775508CN
China post says it delivered order on Aug. 2, 2023, however we did not receive and neither did any of our neighbours. We have contacted seller and they said that according to China post the item was delivered. Can you provide proof of delivery. We have checked our security cameras and no one delivered anything to our home or to our neighbours. I would like to know what happened.
Thank you.

I bought an item from Brilliant planet through amazon on the 26/11/2016. Item tracking number is OWEAA0015671829YQ, the carrier is CHINA POST. I have followed this order upto now (11/01/2017) and it has not been delivered. When i do the tracking, china post has no information as regards to this item yet the seller is assuring me that it was delivered. May i know where china post delivered this item to in Edinburgh?
