My wz stats isn't showing up? Help please needed!

Hello, I recently tried to see my stats but it keeps giving me an error code. I linked my batte.net account still nothing , I don’t know if its a bug or something else. If you can help me out that will be amazing thank you. My battle.net user is iiXerow#1682.

Hi, we no longer support call of duty, as Activision no longer provides stats.
