What a mess.
i got 2 emails on both banned accounts : After further review, this sanction was removed
a third email : We have confirmed that your account was involved in cheating.
And finallly tried to log in on both accounts and accounts are unlocked hopefully.
Seems that the appeal working as the anticheat. false positive emails.
it looks like the EA service crashed or something else during gaming cause of the windows update, but they didnt give any informations about the real problem caused the ban.......
