Seller claims to have shipped my package (tracking #LW239379810CN), but tracking status remained as "A tracking number was provided" for several days now on the selling platform. I contacted seller, and he claims that he has contacted the logistics company (China Post) and that they told him it arrived at the airport and will update soon. It's strange, since I've tried tracking this package on the actual China post website, and there's no update, yet the seller is able to find out "where" it is. I think the seller is lying. Someone help.

YT2117421272087913...this is the tracking number I was provided for package shipped on June 22nd By Etracta. Please advise on status.
Thank you

I was expecting the package from China to US with the tracking number provided as UF529387457YP. The sender happens to write the wrong address, and I would need to contact the US post office to set up new delivery address. However, when I provided this tracking number to US post office, they could not locate anything. It seems that it is a tracking number in China post system, but not the US one. Would you please advise what is the corresponding USPS tracking number for UF529387457YP? Thank you!
