CC already cancelled. Still getting billed.

Please go back to Adobe Chat.  Hopefully, you will get a representative that will be more helpful. Make sure that you mention that you have proof of cancellation.

Tana, I am very sorry you were cut off while interacting with members of our support team. We have been trying to contact you. Can you please use the process listed in https://helpx.adobe.com/x-productkb/policy-pricing/customer-support-portal.html to make updates to your active support case ADB-27987215-V2F3. The case will automatically close if we do not get a response.

The same barriers that blocked you from chatting with us could affect your ability to interact with your support case, Tana. If you are unable to complete the steps listed in https://helpx.adobe.com/x-productkb/policy-pricing/customer-support-portal.html please use a different device. Kglad's advice regarding a browser that allows popups and cookies is also applicable to interacting with web forms.

Thanks for your patience, Tana, and we look forward to your update! Please bookmark https://helpx.adobe.com/x-productkb/policy-pricing/customer-support-portal.html in case you need to make any future updates.

there are 3 ways to contact adobe; chat, phone and twitter:

chat:
use a browser that allows popups and cookies
and click here, https://helpx.adobe.com/contact.html?rghtup=autoOpen
in the chat field (lower right), type AGENT
be patient, it can take quite a while to reach a human.

phone:

twitter:
tweet @AdobeCare

p.s. if you're contacted by anyone (via email or private message), it's much more likely to be a scammer than an adobe representative. ie, double check for an employee badge if contacted in the forums and look for an adobe.com domain in the email address if you click reply to an email. then check again and be very suspicious. any other method of contacting (or offering to contact you) is almost certainly a scam, https://community.adobe.com/t5/using-the-community-discussions/staying-safe-in-the-adobe-support-community/td-p/12919684/redirect_from_archived_page/true
