When I wanted to track the delivery of AT616143272CN, it says that the delivery has been failed on January 16th (Lodz, Poland) without giving any reason. I want to track the parcel via the local post services but do not know which local delivery company has attempted to deliver the parcel. Could you share this information with me?

My package sent from Peking to Berlin via SF.Express. says "inbound failed" after it is out for delivery in Germany.
I would like to know what exactly does this mean, like shouldn't inbound failed means that the package is stuck at custom? Is it even possible that a package is inbound failed after it is out for delivery?
Also, I would like to have suggestions on what to do and who to contact next.

Nobody tried to contact me, didn’t call. But the delivery failed. Where can i pick up my package? Waiting for your response, thanks
