Q: When I recived my iphone6 the case was been opened

I ordered an iphone6 64G gold last month. Toady when I get my package I found the case in side has been opened (no plastic wrap)

I check the order I found the item should have "Signature required" but I checked the name on website I dont know recognize the name. I checked the phone is perfect and not been activated. Can I go to apple store and replace another one? I was going to send it as a gift to friend.

Thanks
