Hey friend, I’ve gone through almost the exact same situation as you. You can check my previous posts for the full details.
After reaching the appeal limit, my penalty history no longer shows any active sanction, but my account is still locked and I still cannot access the game. I tried submitting new appeals and contacting live support, but just like I described in my posts, the submission page says the case was created successfully even though no actual case appears in my history. The live chat option is also completely unavailable to me.
At this point, I basically have no effective way to contact EA Support anymore. It feels like every possible appeal channel has been cut off.
I preordered the PRO edition and played around 260 hours from launch until mid-December. I’ve used this EA account for nearly ten years, from Battlefield 4 all the way to Battlefield 6, and I have never been banned for cheating or any other violation before this.
What makes this even stranger is that a few days ago I saw another post in the Chinese Battlefield community. The poster said one of his old alternate accounts that he previously used for Battlefield 5 was suddenly banned in Battlefield 6, even though the account had apparently not been used for a very long time. Based on the Steam login records and EA login records he shared, the account had not logged in recently, and the account did not even own Battlefield 6 in its game library. Yet it was still suddenly banned a few days ago.
If you’re interested, I can share the link to that post with you.
