I have been attempting to cancel our subscriptions (3 licenses) but have not been able to so this online, by email or by phone. I can't delete the card details so that it will not auto renew next year either.

Hi ​@KNIGHT31786564xfej, 
 

Thank you for reaching out and we are sorry to hear about the difficulty you have experienced trying to cancel your subscriptions.

We wanted to check whether you have tried cancelling directly through the Adobe Admin Console, as this is the recommended path for Creative Cloud for Teams licenses and is separate from the standard Adobe account page.

Please sign in at https://adminconsole.adobe.com, go to the Account tab, scroll down to the Plans and licenses section, select Manage for the plan you want to cancel and then select Cancel Licenses.

If the Cancel option is not visible in your account. In that case please go to the Support tab in the Admin Console and select Start chat to contact Adobe Customer Care directly who can process the cancellation on your behalf.

For full details please refer to: https://helpx.adobe.com/business/teams/setup-and-onboarding/manage-your-account/cancel-creative-cloud-for-teams-licenses.html 

Please let us know how it goes and we will be happy to assist further.
