If you cancelled in the 14-day frame of the start of your paid subscription, you will be refunded automatically. If you cancelled after that date, you are not eligible for a refund.
To check if you really cancelled your subscription, go to https://account.adobe.com/plans and check the status of your plans. If you see an active plan, you did not (yet) cancel, but you can do so, by clicking “Manage plan”.
With a successful cancel, you will get an e-mail.
Refunds are processed manually, so allow 5 working days for the refund to be processed. Weekends and Sundays are non-working days. Some banks also need 2-3 days to account the refund.
If all this is not working for you, you may 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. Pop-up blockers need to be disabled! If the chat window fails to open, or is non-responsive, use a different device to start the interaction.
