Been busy with school and stuff so haven't had time to play lately, I was wondering how I cancel my subscription so I'm not paying for something I'm not using?

I found this article in the support center

Except there doesn't seem to be a button to cancel like it indicates.

I found how to unregister my credit card, but I'm still getting emails saying I'm going to be billed.

Thank you.
