I have very terrible results with China Post delivery in last few months.
In February-April 2018 I bought some items from China and USA. Both were either shipped, received or transit by China Post.
The US parcel number CJ162712335US was shipped from US, left Tokyo on March 7th, entered China on March 8, ever since it was showing on route and then recently it says "No record". It has been 100 days and it has just disappeared in China (the USPS says the status is expired). It contained 2 products.
Another US parcel CY031556986US has left Bejing, China on April 28(!) 2018 and also disappeared, though it says on "on route". USPS status is "expired". Both US parcels are International Priority Mail parcels.
The China parcel BF8022670448 has been shipped on February 2018. It says: Shipping info received, Shipping carrier China Post, Tracking number BF8022670448,
but also disappeared. It also contained 2 products!!
This is just terrible! service!
