I accidentally subscribed and now I'm not getting a refund. What should I do?

Did you ask for a refund?

To request a refund for apps or content that you bought from Apple click on this link --> Request a refund for apps or content that you bought from Apple - Apple Support

If you were refused a refund:

The people responding on this support forum are users like you. We have no special access to Apple information or your accounts, so unfortunately all we can do is guide you to the information Apple does provide. Apple, however, does not have much on its criteria for refusing refunds. Here are two sections from the U.S.A. version of Apple Media Services Terms and Conditions - Legal - Apple Media Services - Apple You can see if the terms are different for where you live by clicking on this link Legal - Apple Media Services - Apple select your location and then your language.

- "All Transactions are final."

I understand this as meaning Apple is starting from a point where any refund is considered an exception. Apple may provide a refund but can also simply say no without having to provide a reason. I understand this can be frustrating but by using the service you agree to the terms.

- "From time to time, Apple may suspend or cancel payment or refuse a refund request if we find evidence of fraud, abuse, or unlawful or other manipulative behavior that entitles Apple to a corresponding counterclaim." Remember that Apple has no way of removing a purchase from your device. They have to trust you are being honest when asking for a refund. It may be certain refund requests might be considered suspicious or excessive.

According to https://reportaproblem.apple.com/static/en-us/privacy.html , Apple uses an automated system to detect fraud. Your request may not have met the automated system’s criteria for a refund. If you feel you want to discuss a refund request with a person, try to contact an Apple representative by email —> “If you disagree with your final decision, contact dpo@apple.com “

Subscribed to what? Sales are final and refunds are discretionary, but if you want to request one you can go to https://reportaproblem.apple.com.

If you forgot to cancel a free trial and now found you have a subscription, I can only recommend in the future to set a reminder so you do not forget. You just need to do it a day before the subscription start date to prevent the charges. It is as easy as using Siri and saying "Remind me in xx days to cancel my free trial".

Otherwise there is no accidental purchase, since it requires you to double click the side button with the amount showing on the screen, followed by verification with FaceID or Passcode. That requires an intentional action on your part and not done by accidentally tapping a button on the screen.

I know that is not helpful in your current situation, but it is Apple's decision after you request a refund. In most cases, all transactions in the App Store are final, but at times Apple may provide a compassionate refund. It should never be expected though.
