Achievements aren't unlocking

I've been trying to unlock some achievements on wwe 2k15 and I cant for the life me unlock them. There's one where I have to become champ three times, done it four times today and it still states my old previous amount of 33% completed. Help!

I'd call MS support.1-800-4MY-XBOX.See what the have to say.You got nothing to lose.Good Luck.

@brimmul777: thanks a bunch man, I'll call them when I get off work.

you should also check xboxachievements.com to see if there are any bugged achievements

It's a known issue... it's noted on the Xbox Live Status page. They're fixing it.

mine have been coming thru like a day later

They seem to be starting to work normally now, but every now & then one won't add on to my total. So still not perfect.
