Rocket car problem

[GLRHotrodRednek]

Hi fellow racers.
I used the code to receive my free Rocket car but it’s not in my garage. I re-entered the code but it says the code has already been used. Any idea how I can get another code or at least get my car?

Promotional DLC: Chryslus Rocket 69

This car is being added to Forza Motorsport 6 to celebrate the release of Fallout 4 (Bethesda Studios, November 2015). This car model was added to the game menu filters with the April 5 content update, and includes a Badge for Chryslus in the Manufacturers section. Players must redeem a DLC code sent via Xbox Live system message in order to see this car in the Buy Cars menu and add it to their garage.
