ok, long story short… I preorder forza 6 ultimate edition and the ad said I will receive 10$ back voulcher code. however, this never happens. I contacted the Microsoft support and they told me to write here… that’s it 
thanks
Where did you purchase it from?
contact whoever you bought it from…its completely their responsibility to organize that
I didn’t get $10 back either.
contact whomever you bought it from…if they advertised it you need to get it from them
i know there was $10 gift vouchers advertised on the microsoft store on certain games at one stage…didn’t know it was for Forza 6 though
