Black Ops 3 season pass not working

I entered my BO3 season pass code and its not working. If I try to re-enter it is says the code has already been redeemed. I even tried doing what another feed said and went to games, highlighted COD, went to manage games, and its not there. Any help?

Questions about Black Ops III

I thought I was buying Black OPs 3 game, instead I got black ops 3 season pass, but it won't download, can I buy just the game & the season pass will download or will I have to buy the whole bundle?

 

Call Of Duty: Black Ops 2 Season Pass (LOWER PRICE ASAP)

The price has not reduce for Call Of Duty Black Ops 2 Season Pass. I feel I'm paying too much money since Call Of Duty Black Ops 2 is a 6 year old game. The season pass should get reduce because Call Of Duty Black Ops 3 Season Pass
gets reduce or discount price. Time is passing and Call Of Duty Black Ops 4 is arriving soon. It's time to give Black Ops 2 Season Pass a discount. The price is out rage since not many going to buy season pass anymore. Microsoft is ripping $10 more at Microsoft
Store on Xbox One. It cost $40.00 in the Black Ops 2 store and cost $49.99 at Microsoft store. It's a ripoff. Please give 90% discount on the season pass. It never going to sell if you keep it at the same price for years. Thank You - P.S. Keep
up the great work Xbox and I can't wait for the massive updates.
