Diablo 3 Achievement Problems

Yesterday I got three achievements for my account: Butchered!, The Last of the Horadrim, and The Comfort of Strangers. When I logged on this morning I no longer was credited for getting these achievements, but I still had the in-game challenges completed
for beating the bosses and quests. I went back through the game and re-completed the pre-requisites for the achievements but wasn't awarded them once I finished. I tried doing a full power cycle, and deleting and re-downloading my profile but neither worked.
The first time I contacted Xbox I was told the problem was on blizzard's end, but then blizzard told me it was Xbox who was responsible. The only solution I can think of is to beat the bosses on Hardcore and see if that grants me the achievement, but I don't
really want to do that.

Metro Redux Achievements not showing up alone with other BS

I also have 4 achievements for Diablo 3 locked because of the problems last night. They should pop within 48 hours so give it till then for yours to pop

 

Diablo 3 confirmed for 360

Achievements are up:
www.xbox360achievements.org/.../achievements

 

If they aren't unlocked, then you'll need to make a completely new save to attempt them again. Once the challenge is complete, you can't complete it again. Achievements need the challenge to complete in order to pop the achievement.

 

I just beat the Butchered! achievement on Hardcore for the first time, and got the new challenge and sigil for beating the boss on that difficulty. This didn't give me the achievement either though. Shouldn't it have though, because even if I played hardcore
mode as my very first character it would award the achievement the first time I beat the boss. I just don't want to delete my game save, becasuse I have so much progress with it

 

i have all level 70 classes but no achievement anyone know why?

 

Beating it on Hardcore unlocks a different challenge, so that won't work.

PerpetualKings; I've heard of no issues with this achievement aside from people downloading a gamesave with it already unlocked and they don't know why the achievement isn't working (I'm not accusing you). Also, please make your own thread and explain the
issue fully.
