I got my response too which was the same generic thing:
Hello,
Thanks for contacting us about your account action.
We got your note and did a full investigation of your account. After reviewing your case, we determined that we took the correct action in accordance with EA policies and procedures.
What this means
We have confirmed that your account was involved in cheating. Because of this, we will not remove the sanction on your account.
You break our rules(https://www.ea.com/terms-of-service#section6) if you:
• use software that interferes with or disrupts an EA Service or another user’s account.
• use undocumented features, exploits or cheats in-game that disrupts an EA Service or another user’s account.
• use software or cheats that disconnects other users from the EA servers.
Any questions?
• Read up on how to play by the rules at https://help.ea.com/en-us/help/faq/play-by-the-ea-rules/
• Review our full user agreement. This is what you agree to when you make an EA Account or use EA services: http://www.ea.com/terms-of-service
Thank you,
EA Terms of Service
I have resumed my case informing them that I have not used any cheating software, and would like them to clarify exactly which action I took that could be deemed as cheating. I play with a Battlefield clan and want to play, but I cannot justify making a new account and buying the game game again with the fear of being banned again at random.
I don't expect much back, going off what others have said.
I honestly just feel robbed.
EDIT: Exploits lol, half the community ride Hovercrafts up buildings. Maybe that's the ban?
