Adobe Automatically renewed a cancelled membership without permission

The key thing here is proof of cancellation. Did you get an email confirmation or any correspondence from Adobe that your cancellation was successfull. If yes then you would have an easy way out of this error and should be refunded and cancelled without a fee. However, if you did not get the confirmation then we have a problem, many a times folks don't verify if the process was done and it fails due to some reason thus causing the situation you are in.

Anyhow, contact support as advised and discuss whatever your specific case is, if you have the proof show them that and get it done quickly. Best of luck

do you have a team/enterprise subscription?

if not, use a browser that allows popups and cookies and contact adobe support by clicking 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

p.s you can also use phone (but chat is usually quicker), https://helpx.adobe.com/contact/phone.html

p.p.s. you can also use twitter to tweet @AdobeCare

p.p.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
