استرداد المبلغ

you can't cancel if there's a payment problem.  ie, you have to fix that payment problem and then you can cancel.

to fix the payment problem, https://helpx.adobe.com/manage-account/kb/fix-failed-missed-payment.html

and 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.
