My package is stuck in "plane landed" for more than twenty days, how can I solve? shipping number CY032062559CN.

I require a Bill of landing on a package (Tracking n°RG025430947CN). It's said to have arrived on my country yet my Postal Office tells me its not. I need the bill of landing to provide evidence of the package's entrance to my country and make a formal complaint to my post office. Thanks in advance,

Juan.

My order: EB809606559CN seems to be stuck in "Plane arriving".
How is it possible for a status to be 'Plane arriving'? I mean, is it in the air, and they update the status before landing? I don't understand.

It also seems a bit strange that in the history, it says 'Airlines received' up to 5 times:

I also have another package in the same situation: EB809617389CN. Can you tell me what's happening?

Thank you very much!
