The status of the above package according to the package tracker: Delivered.
But I didn't take it, I didn't get anything. The neighbor didn't pick it up either, the post office doesn't know about it, I didn't receive any prior phone or written notification about the delivery either. I don't know the name of the freight company, so I'm asking for your help. Where can my package be, who received it?
Sincerely:

Miguel

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?
