HW Achievements not adding to milestone on halo waypoint

I dont know when this is going to get fixed, I dont know how it happend, I know that multiple people on these forums are having the same problem, and I am one of them, if anybody has a solution for this please share it, cause ive tried everything to make it work and it never did. Some poeple said to wait a couple hours, did that, nothing happend, some people said wait a week, its been 2 weeks and nothing, some people said play an online match, i did and nothing happend. And one dude said contact 343 lol?

So if anybody knows how to fix this let me know thanks
