The new account management screen

My account is currently in the 'pending' status right now and I would not like to pay for another month subscription. No hard feelings, I would just like to take care of other pressing matters before Cataclysm come out.

So my problem is I can't find the 'cancel subscription' button any were on the new account management. I removed my method of payment from my account, but it continues to appear whenever I click on 'Set Up Game Subscription'. I also would like to know if I will be charged for another month if I were to cancel my account on the day of my recurring subscription.

Thanks in advance for looking at this!
