Req pack didn't let me unlock one of my packs

I bought the warzone req pack, I tried unlocking one and it said there was an error, I tried opening it again and then it said I had already opened that pack, even thoughoul I didn’t get any of the items, I tried reloading the game and my req pack was just gone, but I didn’t get any items!

Hello Clos,

On rare occasions, a REQ Pack will open without displaying the full animation. If this happens, the items will still be placed directly into your inventory. If the items are not immediately visible in your inventory, please perform a hard reset on your Xbox One and the items should be there. Additionally, if you’d like to check from your computer, the items should be in your inventory here on Halo Waypoint as well. We apologize for the inconvenience!
