I was permanently banned due to enhanced gameplay.

Sadly no one here can help with this. You should have received an email with the link on where to go.

Welcome to the club. It has been two weeks and two appeals later and they keep saying they have evidence I was cheating. My account was literally immediately banned the moment I first logged into the game on my PC. Played it twice for a couple of hours on my Xbox, then bought it for my PC and banned immediately. Worst part is that I cannot even play the campaign while I battle the appeals AI. It won’t even allow that.

same here i cant even get my case to go through just infinitely loads and never posts

Welcome to the party i received the same ban and never cheated i got the Phantom Edition on the EA App and played 6 games with my buddies and had some good games and had some games id run around and be sniped constantly called it a night woke up next day boom banned for gameplay enhancement no clue how or what triggers this seems to be a common issue with some people and sad part is EA wont unban your account i dont even think they really go back and watch at this point i feel like these are false bans and they are getting their money either way so they dont even care which is complete bull crap if they have evidence man id love to see it because i know they lyin im not the best nor the worst i carry about a 1.8kd but yet im cheating lmao yeah okay...
