As per the description above, you want to cancel the subscription, Is that correct?
I have checked the details with your current Adobe ID(email) which you have used to log-in on Adobe forums and there is no subscription/license registered.
You can also check the status of the plans from Adobe.com>Manage Account>Plans and Products or can also refer to help article Account and membership help
For the cancellation, you can refer to the Adobe article Cancel your membership or subscription | Adobe Acrobat, Document Cloud PDF services
If you have the subscription on a different email address, sign in with the email address and take help of the above article for the cancellation.
Feel free to update this discussion for further assistance.
