I have not received the Forza Horizon 3 Pre-order $10 Microsoft Store gift code

I have not received a code for the warthog or pre order car despite me owning halo the master chief collection and pre ordering Forza horizon 3 deluxe edition on the Xbox store. I have received codes before in the past like the Chrysalis Rocket 69 and le
mans ford GT for Forza 6. and the codes are not in the in game messages as some people have suggested.

No I received a $10 digital gift card code from the Microsoft Store for pre-ordering the game. The code for Free Fall came with the game.

Mister Maka I never received the code for the warthog or pre order car in the first place I have been looking in my messages every day but still have received no code for either the warthog or pre order car. I own halo the master chief collection and I pre
ordered forza horizon 3 deluxe edition from the xbox store so I should of received both codes for the cars by now.

Because I was told by Microsoft that if I pre-ordered Ryse, Deadrising 3, or Forza 5 day one editions that I would receive a $10 digital gift card code. Its all over the net, check for your self.

...if you are a rewards member, you would have received 15,000 rewards credits instead of the $10 code.

Is that listed in the fine print or something? This is important information I wish I knew before wasting everyone's time.
