Hi,
it's a pity. Did you read this: http://www.adobe.com/misc/subscription_terms.html.
And here are two links where you can cancel the membership too (I didn't sent them because it's CC):

If necessary and for further questions click through http://helpx.adobe.com/contact.html and if "open" please use chat, I had the best experiences. I quote from Preran: The chat button is activated as soon as there is an agent available to help.
Good luck!
