When will it be delivered?

I am trying to track down a package that was sent via Canada Post to China. I was informed item has already arrived in China on June 10th, however they are unable to view additional details as it will be handed over to the local courier. I recognize Canada Post usually hands it over to China Post. Can you please take a look into this? I need the China tracking number. This is an important parcel as it is a return package and seller will not issue refund without proof.

I hope this email finds you well
I know that China post operates within the ICBC building here in doha, and I ordered a package online from China which is supposed to arrive through China post
It says on the China post website that the package is already delivered but I haven't received it yet, I would like to know if the package will arrive home or if I need to pick it up and where amd when can i pick it up?
