I forgot my account email and can't cancel yesterday's card charge. Please provide your customer service email so I can contact you

Thank you for posting, ​@agile_Butterfly2dc2.

I understand how frustrating this situation can be, especially when you are trying to identify the account associated with a recent charge.

As ​@kglad  mentioned, the account you used to create this forum post is likely the same account associated with the active subscription. Since you are already signed in, I recommend reviewing your account details and plans here:

https://account.adobe.com/

You can also review your active plans and billing information:

If you recently subscribed and wish to cancel, you can find information about Adobe's cancellation terms here:

If you are still unable to locate the subscription details after reviewing your account, please let us know what you see under Plans in your Adobe Account, and the community may be able to provide additional guidance.

Please update this public discussion thread if you have any additional questions, ​@agile_Butterfly2dc2.

use https://helpx.adobe.com/manage-account/kb/unknown-charge-on-bill.html to find the adobe id used to make your subscription.

then 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", you probably have a payment error that you need to repair before cancellation is allowed, https://helpx.adobe.com/manage-account/kb/fix-failed-missed-payment.html
