Battlefield 3 Premium Edition.My account was hacked

Same here, my account was hacked 4 days ago, since the first day I contacted EA for support, they transfered my case to another department and told me to wait for them to get back to me, im still waiting, i really dont think there's much to investigate, i have proof that im the owner of the account, but they didnt care to listen, also this is happening a lot, theres tons of forums where you can read about it, so this is EA's fault.
