Unobtainable achievements in Halo: Spartan Assault

I posted the following comment on the Halo: Spartan Assault forum back in October, and I have never gotten an official reply. I am hoping that reposting this on this forum will help get the attention of someone who can do something about getting the achievements fixed. The unobtainable achievements are in the iOS version of the game.

“There are currently 5 unobtainable achievements. This is due to the achievements being located under the “Game Center” tab instead of the “Xbox LIVE” tab. The 5 achievements are: Pension Plan, Weapon of Choice, Skull Combo, Extra Credit, and A for Effort.
How could 343i have possibly screwed this up? Spartan Assault has already been released on four other platforms. It’s time 343i gets their act together, and fixes a game that shouldn’t have been broken in the first place.”
