2 Free Games with RX VEGA 64 - Question

Recently purchase RX Vega 64 and it should come with 2 free dames ( Wolfenstein 2 and Prey). But i didn’t receive any code to redeem this game in my package. From AMD site see that i need to have AMD Unique ID , and with that i can redeem my games.

How i can receive my code?
Thank you.
