you must refund my money

Adobe's account management works at the minute precise. So, if you take the subscription at 11:43, the first charge will be after seven days at 11:43. 

As you are still well into the 14 days of your paid subscription, you can self cancel and there will be an automatic refund. The refund takes up to ten days to process, however. Be sure that the cancel was effective, by checking the account (https://account.adobe.com/plans) and by checking your e-mails. Adobe sends out an e-mail when you cancel, confirming the cancel and the refund.

If for some reason you can't self cancel, you need to contact Adobe customer service. 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, you need to accept cookies! If the chat window fails to open, or is non-responsive, use a different device and/or browser to start the interaction.

Important: Adobe does NOT contact you unsolicited by e-mail or direct message. If you get contacted by direct message from a person, claiming to be an Adobe employee, look at that profile and check if they bear the “Adobe Employee” marking under their name. Adobe support does not use Skype to give you support.
If in doubt, ask the forum.
