Does it do any good to petition an achievement that you qualified for but the system didn't grant? Can prove completion but keep getting "will refer to Dev's" as a standard reply and never a solution.
They are probably (from the sounds of your responses) treating it like a bug, and once the bug is fixed, everyone with the problem will be fixed also. I don't know for sure, but my guess at why they haven't singled you out to fix yours, as it wouldn't help others having the same / similar problem. Yther Ore.
I have been granted achievements in the past but it took SS, a video and multiple people and messages to prove our point.
