The delivery address is incorrect. The courier did not deliver the package to the incorrect address.
The person living at Corso Vittorio Emanuele 6 does not have the package.
Who is the Italian courier company that was supposed to deliver the package? Thank you.

I accidentally put the wrong address on my package and it says it was undelivered so my question is who would I contact?

I sent a parcel from US to China. Tracking information says held at post office and undelivered.
What do I do?
