This is an open forum, not Adobe support... You need Adobe support to cancel a subscription
-or by telephone http://helpx.adobe.com/x-productkb/global/phone-support-orders.html
If you want to cancel your subscription, they say you have to speak to a representative. Then when you call, they don't answer the phone. You can also do it by chat. But if you type in a message, nobody will respond. A great way to keep customers.
