I finally received mine but there’s missing part

Hello I finally received my Gameshell today. I just opened the package and noticed that “1x GameShell - Standard Rear Shell (Basic Colors) - Blue” is missing. Where should I contact for this issue?

Solved!

I found out the rear part was out from the main package box for some reason. I just noticed when I through away the package envelop.
I’m sorry about the false alarm.
