I was sent a package (RR117255886PL). The system says it has been delivered few days ago. Unfortunately I didn't get it. I live in the University of Science and Technology of China student dormitory, probably sobebody collected the package and it awaits in some office here. The sender didn't provide my telephone number (i.e. +8618656014153). What should I do now?

My package says delivered in tracking app. but i didnt receive it, suspicion i got track& trace code from seller thats belonging to parcel to other person. Can you please tell me where/ to who package with tr&trace LT253507611NL was delivered. I live in Rotterdam/NL and i didnt receive it for sure.

Im writting you because my package didnt came.
And contact is china post.
Do you have any answer for me why i didnt get the package?
i buy the package on amazon.
