Is waypoint telling you that you didn’t unlock the recruit, prodigy, etc achievements even though you have the gamer score for them? Feel free to post as many rants as you wish in this thread, 343 needs to be made aware of this… plus I’m sure you would like to get your money’s worth out of the champions bundle.
Erm… I don’t see a ‘No’ option on the voting poll, so I shall instead simply Abstain.
Also - Are you sure you’re unlocking the proper achievements? I’ve played it on the xbox (Don’t have a tablet or a Win8 system) and they all unlcoked for me fine. Entered my code and got the stance and boot emblem 
Also, not sure if this really belongs in the Halo 4 forum… These might be more appropriate forums to place this in:

edit As for the Champions bundle… I’m pretty sure everyone’s got their money’s worth out of that. Additional stances, new maps…
That’s a pretty big overreaction, especially because you’re entering in the wrong codes. The 3 codes–Recruit, Prodigy, and Able Spartan/Powered by MJOLNIR–only work for the Windows 8 and Windows Phone 8 versions of the game. The Xbox One and Xbox 360 versions have one code, and it does the same thing as the three Windows 8 codes. You can find the code here.
Next time, ask questions before you jump to assumptions.
