The game could be a really easy missing item SE.
You sign for it as normal etc etc and then get in contact saying you opened it up and there was no disk inside. It will be so light they cant verify it with weight so even though it was delivered there is no way for them to disprove your claim - should be an almost certain successful SE.

Any obstacles, if you push enough you should get through as like I've said they dont have much of a leg to stand on in terms of disproving your claim.
