I wonder what terms of the rules you broke. Wait for someone from the support to reply to your post. They will definitely help you clarify this case or at least should tell us which poin of ToS you broke. It just takes time, so you will need a bit of patience.
Can they do that to other users in the past that are still hoping that they can have their cases heard by the support? Either they're fabricating claims that they are solving issues now or they won't solve it, also it's a bit sad and pathetic of you to be this high in rank but so desperate to join a campaign, good luck joining other campaigns in the future when 1xbit is finally gone.
