Darktide promotion code?

I recently bought a new video card that has the promotion for the Warhammer: Darktide. I bought it a few days before the game released, but the promotion was listed on the site at that time; I haven't gotten the promotion code or information about how to download the game yet. Can someone from Micro Center contact me directly, or let me know how I can redeem this?

Also, the Chat feature for support on the main Micro Center site doesn't do anything when you click on it.

Thanks

George
