To cancel your subscription: https://helpx.adobe.com/manage-account/using/cancel-subscription.html

To (maybe) get a refund you would need to contact Adobe directly, using one of these channels:

Chat support: https://helpx.adobe.com/contact.html?rghtup=autoOpen
(make sure pop-ups are not blocked; type "Agent" to chat with a real person, or via phone, during working hours)

Twitter: https://twitter.com/AdobeCare

There's no email support.

Beware of people contacting you via the forums' messaging system pretending to work for Adobe! Only those with an "Adobe Employee" tag under their name are legit. Also, Adobe will never offer to contact you via Skype, or use an email account that's not under the adobe.com domain...
