REFUND

no one can cancel for you.  you must cancel yourself.

make sure you're aware of the cancellation terms by selecting your plan type (at the top of the page here), https://helpx.adobe.com/manage-account/using/creative-cloud-subscription-terms.html



and for info on how to cancel your subscription, this page describes the few steps involved, https://helpx.adobe.com/manage-account/using/cancel-subscription.html

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.



if you're unable to follow the steps described, you'll need to await help from an adobe employee for the next step.  (if you don't get a reply here from a badged employee within 24 hours, repost.)
