Charged for Free Trial

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

@jennifer_8902 When you sign up for a free trial, you are typically agreeing to a subscription that will automatically start and charge your payment method unless you cancel. The terms state that the trial is for a specific period (e.g., 7 or 14 days), and if you don't cancel before it ends, the charge goes through. If you cancel on the very last day of the trial, there can be a discrepancy between your time zone and Adobe's. The cancellation must be completed before the trial period officially ends in Adobe's system (this is the main reason why I never ever try a trial period for anything!)

Is it possible the cancellation process didn't complete successfully. This could be due to a technical glitch, a pop-up blocker, or simply not clicking the final "confirm cancellation" button. Check your email for a cancellation confirmation from Adobe. If you don't have one, the cancellation may not have gone through.

Also, have you previously have a free trial on the same account? Adobe's systems may recognize this as a pattern and charge you even if the trial is "cancelled," as they may determine you're ineligible for the free trial.
