All the emails have said is that EA considered there was a violation and the dispute is being reviewed other than those bare statements there has been nothing of the type of correspondence you describe. I offered all information I could while travelling, which was somewhat limited, and now home have confirmed I can provide more but none has been sought. I reviewed the ToS rules and none of them apply. I just used the phone app on a plane wifi while travelling. The same use lead to a mistaken ban in August, last time when I was on a plane, but that was reversed the next day. This time exactly the same thing has happened and 10 days later all I have been told is that the issue is being considered, which itself is worrying since a) EA do not inform people what they consider the issue is and B) I have sought to provide information when I returned home and there has been no means of providing it. My son in particular is very upset at the family losing out on the pre-release and the rewards. I have dealt professional with international banking fraud investigation agencies that are more forthcoming that EA have been.
