Who in the UK would have delivered my parcel as only have the tracking china delivery label with China tracking number. Retailer in China says contact my delivery company but how do I know who this is. AS033367424CN tracking number for China Air tracked for 2 weeks no problem arrives uk sats delivered ?? ( by who ) as tracking does not show its not been delivered and its a kayak so not a small item how can I locate it

I have checked the tracking of my parcel which is saying that it has been delivered but this is not true.
The delivery address has someone there the whole time and no parcel was delivered or any attempt to deliver has been made.
If there is the opportunity to contact the courier I would be grateful to have their contact details to make a direct enquiry.
The tracking number for my parcel is: AM075852903CN
Please let me know as soon as possible.
Thank you
Christian

AT107663885CN is my tracking number. 17Track said my parcel was delivered, it wasn't. I live in an apartment, there is no where to leave, any parcel. I get parcels delivered, they either call, or leave a delivery notice. Nothing was left, no neighbors who delivered my parcel. Thank you MaryAnn Zamko
