Fallout 3 promo code disappeared

Hello.

Promotion name: Free Fallout 3 code with digital purchase of Fallout 4

Date of purchase: 10th of January 2016

Issue: The message with my Fallout 3 code has expired

I bought Fallout 4. It was promoted that I will get an activation key to Fallout 3 for XBOX 360. I received a message with this key, but now this message disappeared. How can I get it again?

 

Fallout 3 Code deleted

• Promotion name: “Free Fallout 3 code with digital purchase of Fallout 4”
• Date of purchase: “[13.11.15]”
• Issue: I deleted my fallout 3 key by a mistake. Please help me.

 

Since that game is region locked, there is a chance the code would only work for the region it is made for.

 

Thanks for your answer. I would like to know if the key works, is he gonna play the game in french or in german (whick is the only language when you buy it i switszerland)?
