This happened to me 2 years ago. The holiday help UPS driver was delivering all my shipments to the local drug dealers in the area in exchange for goods.
Best you can do is call where you bought the items from and declare them stolen.
If it was UPS, try this number 203.799.8011. Insist on finding out who the route driver was that day.
Good luck. I lost 3 separate packages in my situation and UPs denied any wrong doing.
