Thank you for posting, @different_thinkbe1d.
I am sorry to hear about the difficulties you are encountering in managing your subscription.
As Kglad suggested, please start by reviewing the plans and billing information in your Adobe account:
https://account.adobe.com/plans
There is an active Adobe Acrobat Pro subscription on the account that is currently past due. When there is an outstanding balance, Adobe may be unable to complete the cancellation until the payment issue is resolved.
Please review and update the payment method associated with the subscription:

Once the payment issue is resolved, you should be able to complete the cancellation process through your Adobe account. You can review the cancellation steps and terms here:

If you continue to have difficulty canceling the subscription after updating the payment information, then please don’t hesitate to contact us directly at https://helpx.adobe.com/contact.html?rghtup=autoOpen.
Please update this public discussion thread if you have any additional questions, @different_thinkbe1d.
