I am sorry that your account was banned for a violation that you presumably didn't commit but it has little to do with EA dont wanna help. Its all about practicality. Imagine the thousands of unban pleads that EA receives every month. "My brother played on my account and cheated", "I played on an internet cafe and forgot to log out", etc. Sure; you can show that someone logged on from other IPs but thats just a click away on your VPN.
So the only plausible way to deal with all such cases is too clearly state that its the account/hardware from which the violation occurred that is banned and NOT the physical human doing it. And I dont want to sound harsh but the 2-step verification method is secure enough to prevent all kind of "normal" hackings of accounts.
