My package was apparently delivered to the wrong person. It was signed for by a person unfamiliar to me. It was from amazon, and it was addressed correctly. What now? Can the customer center help me?

Contact 1800 pick ups, file a claim for a missing package

Call the 1800 number and they can see where the driver delivered the package

Customer Service!

I would recommend contacting human resources at ups to see if they can help you at all.
