Well if it's any help, I once saw someone stealing something from Game and he got away with it too. I stopped using Game at the beginning of this year. HMV is much better. They provide refunds too and some of the games are "buy 2 for Ł15". The best place for games though is Amazon.
Just don't buy games from Game any more, they had to close 100 shops last year. Serves them right I say.
