Gears of war preorder beta code issue

I had preorder gears of war ultimate long before it came out and started playing it at midnight the night of realease, and my two friends has just receive there gears of war 4 beta codes and I haven't as yet

As noted in the
Gears 4 Beta FAQ - The codes are being sent out in waves, however they are no longer being sent in chronological order.

Starting tomorrow morning (pacific time), we will be sending out a higher volume of codes to help compensate for this change and due to server stability seen during Day 1 of our beta.

I contacted NVidia twice already and have told me to contact Microsoft to check and see if it was successfully redeemed I think my main issue is that I had gears of war 4 preordered on my Xbox when i redeemed the Nivida code and cancelled my preorder on
gears of war 4 to ensure i wouldn't get charged for it

Hey there royalt1999!

Just to clarify, did you not receive the code for the Gears of War 4 beta or for Gears of War: Ultimate Edition? If you did not receive a code for Gears of War: Ultimate Edition in the bundle box, you will need to reach out to the original purchase retailer
for further assistance. If you are referring to the Gears of War beta, those codes have not been sent out yet. Thanks in advance!

Hey UD BlueHen1991!

The Gears of War 4 beta is not a code included in the box. Instead, you should receive the code close to when the beta begins. We do not have any information to share as far as the timeline for the Gears of War 4 beta will be. Be sure to launch and play
some Gears of War: Ultimate Edition while connected to Xbox Live in the meantime!
