Subscription Amount Deducted in the Free Trial Plan

adobe's free trials are usually 1 week followed by automatic enrollment in a subscription with a 1 week grace period during which you can cancel without penalty.

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

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

if you want to cancel but are unable to follow the steps described in the "how to cancel page", contact adobe support.

there are 2 ways to contact adobe; chat and twitter (now x):

chat:
use a browser that allows popups and cookies, and click here, https://helpx.adobe.com/contact.html?rghtup=autoOpen
in the chat field (lower right), type AGENT
be patient, it can take quite a while to reach a human.

twitter/x:
tweet @AdobeCare

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.

Hello @raj_4477 although you were in the right forum (Adobe Express) I have moved your post to Account, payment & Plan as that is what your query is about. You will need to contact Adobe via the chat help to sort out your account. 

You can get help with your account billing here. Use a browser that allows pop-up windows, and look for the little chat bubble.

Also, AdobeCare on Twitter/X are very helpful, so give them a try too. Don't put any personal, identifying information in your initial tweet, just the outline of your problem and they'll tell you what to do.
