Hi ​@Adrisantos ,

I looked into your account details, however I could not find any active plan listed there. If you have subscribed using a different email address, please follow the steps listed in this article: https://helpx.adobe.com/in/manage-account/using/cancel-subscription.html

I hope it helps.
