please help, I am trying to cancel my subscription but there is no 'cancel plan' button

Good morning.
Acrobat Reader is a free product, so I don't think it needs to be canceled, but I think it's about other products.

Since the cancellation button may not be displayed to confirm the charge on the day before the billing date, it is necessary to contact customer care in this case (If the button does not appear in the document, contact the customer (There is a description)
Also, please note that if you pay monthly on an annual plan, 50% of the remaining period may be charged as a cancellation fee.

Hello,

I have the same problem. The day I subscribed, I decided to cancel. But the resiliation procedure doesn't go to  the end and I keep registered and already paid twice 17,90€. I paid through paypal and have put a claim. Waiting for answer. I will also make opposition at my bank to any debit of Adobe. Adobe is just unfair. .En français on dit "un salopard" I am french.
