Missing download codes with xbox one x

Today the Xbox one x that was meant to come with two download codes for Forza Horizon 4 and Forza 7 Motorsport (ordered from Currys PC world) arrived. However, after emptying the box and setting up the xbox we couldn't find the codes. We checked every
leaflet provided and here were no codes for the games. Any way we can get another code because we payed for it!
