Adobe's online account system can neither cancel nor refund you without a valid payment card on file.

You see how that works?

Thanks for tagging me, @Peru Bob!

@art84897186 I am sorry for any confusion. I show that you have created two different accounts, please see https://helpx.adobe.com/enterprise/kb/enterprise-id-faq.html for information on how to sign in under your individual account that has the active subscription you have been using for the last three months.

Before you will be able to delete your account we will need to have payment for the services you have utilized. Once you are signed in under the individual account you can use the steps in https://helpx.adobe.com/manage-account/kb/fix-failed-missed-payment.html to update the account and pay for the services rendered.  It looks like you also attemtped to change the name on the account with the active subscription, @art84897186 so you may also need follow the steps in https://helpx.adobe.com/manage-account/using/edit-adobe-account-personal-profile.html and add your correct name and any other required information to the account.

Finally, @art84897186 , once your subscription is paid for and current you will be able to complete the steps in https://helpx.adobe.com/manage-account/using/cancel-subscription.html to cancel your subscription. You will want to bookmark this discussion and then use the information in https://helpx.adobe.com/manage-account/using/delete-adobe-account.html to request that the account be deleted, once the subscription is cancelled and any refunds or charges have been settled, @art84897186 .

Could you please check the OP's account?

>used cdkey for one month

I don't recognize cdkey as an Adobe product

What do you see for your account at https://account.adobe.com/

You probably don't have a valid payment method on your account, and you have a payment due.

Or you may have a penalty to pay before canceling.
