Won’t give me a refund for something I don’t use

In addition to what the others have said, it sounds like your account/credit card information has been compromised.

If it's a credit card, get it canceled now and talk to the issuer about a refund.

If it's a direct debit from a bank account, log in to the account directly from a known good URL (NO  EMAIL LINKS), change your passwords, and contact the bank to alert them to the fraud. You may or may not get the money back. Also check your account information to ensure that your email and delivery addresses are the only ones on it. The bank may recommend closing the account and creating a new one to ensure that the fraud doesn't continue.

Hi @jj.3000,

Adobe's Annual plans are for a 12-month commitment. Here's a guide explaining the process which should help you find the best solution, and possibly save some time or money:

What You Should Know Before Canceling Your Adobe Trial or Subscription

But as with any service or subscription, whether you actually used it or not is independent of having signed up for it. (Possibly Adobe might make an exception if it was done by a hacker, but you'd probably need some kind of proof of that.)

Hi,

It's really sad to hear about your terrible experience with Adobe Support.

Since this is a Users forums and not Adobe support Team, we cannot commit on the refund. 

Also, please go to Adobe Customer Service (make sure to sign into your Adobe account first):
https://helpx.adobe.com/contact.html?rghtup=autoOpen will automatically open the chat window.
Type "Agent" in the chat box to bypass the chatbot and be connected to a person.

You may also be able to contact Adobe by phone:

Thank you.
