Have you opened it yet? Did you buy it in Game? I know that Game operate a 14 day money back gaurantee in order to say that you can try before you buy. The other thing is that they cannot refuse to take the game just because it is part of a package - althought there are other reasons why they don't have to. Just as a heads up to you , legally you as a consumer do not have to purchase the console with any other peripherals or games unless included in a package set out by the manufacturer. If they tell you that you have to then just tell them you are going to report them to 'Trading Standards' due to a breech of your consuimer rights and that they are breaking the law. The other thing that will work is if you tell them you want to speak to customer services using their phone and then handing them over. The main Game officer (or any other companies) will say that you are not forced to buy the other items and that you do have a right to buy any items you wish and that a branch enforcing a package is not operating ocrrectly.
Hope that helps in future.
