Can I please get a refund for a billed free trial subscription? I missed the date to cancel it. Would appreciate the help.

>I missed the date to cancel it

You now have a subscription and there is a fee to cancel early

This is a public forum, not Adobe support... other users can't see your account to help
This is the correct way to contact support

- and enter AGENT in the box asking How can we help you?

no one here can do that for you.  you must cancel your own subscription.

You can cancel the subscription and get a full refund if you cancel within 14 days of initial subscription. See https://helpx.adobe.com/account/individual/terms-policies-and-regulations/adobe-subscription-terms.html

So if you are within this time limit do cancel asap.
