Re: [Xbox 360] Achievements Not Unlocking From Offline Playthrough
@awildcoopixe Support has no actual visibility into achievements being unlocked. EA has no way to apply an achievement to an account because the console account (Xbox) goes by the data on the save which has nothing to do with the EA account itself. It doesn't matter who the publisher is for the game, this is how consoles work in general.
As for the case, I had someone take a look to see why it was closed as I do not see any reason which means it wasn't closed by an advisor so you were not blatantly ignored. This could have been the system closing it out for some reason.
On the achievements, Being that it is a console and not the EA app, publishers cannot in any way grant those because they are tied to the Xbox account and saved data, not your EA account specifically. As 360 is now quite old, and Microsoft is shutting down a lot of online services, they may not pop for you.
I did find a few articles relating to this. When you play offline, they should be granted when the console goes back online if everything is stable, a good connection and you earned them.
