Yeah, contact vmk. Ask them what exactly you'd been banned for. It may have been something that happened before that week off, as some bans are not immediate. If you don't hear back from vmk, call them. There is a telephone number for Disney Online. Call them and ask to speak to someone with vmk. Ask them what the ban was for and that it please be reviewed.
I'm sorry, this is about the only thing you can do.
Good luck.
