Code is not working.

Some doubts?

Your Live Region is US?

In case of yes go to the next question, if not the problem is the 1600 ms points only works in US live, the Ms points cards only works for region they are builded (for a sample if buy US, the cards in comun way is the values of 1600 and 4000 points for US
and only works in US, if i buy a Live Brazil card; comum value is 1500 and 4500 points, and try to use in US account the system stop the operation because he didn´t reconize cards from outside of the country of your account).

That card have 25 digit code?

If yes and your account match the region of points you have back to reseller and inform the card dosen´t work and try to use in front of them (if they permit, and show your account to prove you didn´t receive anything)they have the legal obrigation to substitute
in case of card dosen´t work.

I hope i help you and forgive my bad english it´s self learnerd

It could be related to the system outage Xbox Live is currently experiencing. I would wait until this is cleared up and try again. You can always check the status here:

You would want to contact support directly, not through Twitter, for assistance. http://support.xbox.com/contact-us

Thanks for your answer, i already try to use the code on my browser but still not working, then i can't call the xbox support because i'm French and my english is not very good.

During 1 week i have try everyday to use the code but nothing happened.

Have you tried contacting Activision support? I would send a message on their Community Support page almost similar to this one. https://community.activision.com/t5/Call-of-Duty-Forums/ct-p/cod-forums
