I was charged for AppleTV since December, id like to request a refund from December to April 2022.

This is primarily a user-to-user support forum; other Apple users like you. We cannot refund anything. See information in Request a refund for apps or content that you bought from Apple - Apple Support

This is a user-to-user support forum; we have no power to refund anything. Here is how you can request refunds:

Start with this one-stop link for billing questions→Subscriptions and Billing - Official Apple Support. You can review your purchase history to see what you were charged for, cancel subscriptions and request refunds.

FIRST: Review subscriptions, and cancel the Apple TV subscription

NEXT: Click Request a Refund enter your request for each of the subscriptions

Note that you may not get all of them; there’s a limit to how far back Apple will go for subscriptions that were not canceled in a timely manner.
