결제를 진행했지만, 플랜 사용이 안 돼요 !

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, check for a payment problem. all payment problems must be resolved before cancellation is enabled, https://helpx.adobe.com/manage-account/kb/fix-failed-missed-payment.html

Access your Adobe Account (top right of your app screen) and select Manage Account from there you will be abe to access your plans and change your payments under the Billing and Payment tab (unless you've agreed a yearly contract).
