card cancellation

in the future, to find the best place to post your message, use the list here, https://community.adobe.com/

p.s. i don't think the adobe website, and forums in particular, are easy to navigate, so don't spend a lot of time searching that forum list. do your best and we'll move the post (like this one has already been moved) if it helps you get responses.

contact your credit card issuer to cancel your credit card.

if you actually are asking how to remove your credit card from adobe's records, you can only do that IF you have no subscription/trial.  then go to https://www.adobe.com/privacy.html, click contact us and request your adobe id be deleted.
