Go in and delete the payment details under payment options and then raise a ticket with Blizzard asking for confirmation. To be honest it is better than asking here...
I got an email to my main saying the auto-renewal was cancelled. But to be on same side I went ahead and deleted all info from there. Planned on selling the account anways, just look like I will have to wait a few months
1. You have bought 6 months sub the day before the ban.
In this case, you will not be refunded
2. Your account sub will be renewed the day after the ban
In this case, you will not be charged, since the account now longer is active.
