My disk has become broken

Hello
So I was on a xbox support chat and they said I should come here.
Basically my Forza 4 disk broke and I was wondering whether It would be possible for you to give me a code for the xbox live marketplace so I can continue playing the game. I cannot buy the game any where new so that’s why I’m asking here. I have the box and disk which I can show as proof as I originally bought the game from Amazon about 3 years ago and have no receipt as a result. Hopefully you can help me resolve this issue

Thanks!

Amazon has an order history available online when you log in to your account there, and they still sell physical discs for FM4.

Do they? Okay nevermind then xD, Thanks for your help
