Sorprendido.

I don't see any Adobe Stock subscription associated with the Adobe ID you are using here on the forums. Please confirm that you are signed into https://account.adobe.com with the correct Adobe ID.

The trial is 30 days at no cost, subsequently, a monthly charge occurs. That's clearly stated as this on the screen where you make your purchase. You can, however, still cancel free of charge in the 14 first days of your paid subscription. You will be reimbursed.

To cancel, I suggest you look here: Cancel your Adobe Stock membership

If you can not self-cancel, I would recommend to contact Adobe customer care. Adobe customer care can be contacted by beginning a secure chat session at https://helpx.adobe.com/contact.html?rghtup=autoOpen. If the chat window fails to open, or is non-responsive, use a different device to start the interaction.
