If you are banned - DONT FORGET.

If you've been banned and pre-purchased Legion, Don't forget to fire in for you're refund, This is still claimable even if you used your 100 Level Boost. This is achievable through the Online Help system blizzard has.

Remember to cancel you're subscription. this seem's obvious but there is a lot of people that forget.

I'm not sure yet but I purchased several WoW Token's for gold. If Blizzard has removed all my gold I will chase for that to be refunded too.

Good luck. Have a good 6 months.
