About subscription

Acrobat Reader is free.

Acrobat DC is not free. If that's what you subscribed to, you need to cancel your subscription yourself.

Be aware that if you have did subscribe to Acrobat DC and it is more than 14 days past the initial subscription date, you will be charged a cancellation fee.

If that doesn't work, you'll need to talk to customer support. This is a public forum, not Adobe support. Users, including the ACPs and MVPs, can't provide support for account, subscription, billing, download, or product activation issues. Support for those issues requires an Adobe employee.

Adobe provides support through the Chat function on the contact page or through a phone call. There is no email support.
