I Was Charged Before Trial End on Splice App Downloaded from Apple Store

I downloaded the "Splice" app from the Apple Store, which offered a one-week free trial. However, before the trial period ended, Splice charged my account without my consent. When I decided to cancel the subscription and checked my account, I saw that Apple had already withdrawn the payment unfairly. This early charge is completely unacceptable since I canceled before the trial expired. I demand a full refund for this unauthorized payment. The fact that the app took money prematurely despite promising a free trial is misleading and unfair to users. I urge Apple and Splice to address this issue immediately and process my refund without delay. This kind of billing practice damages trust and must be stopped.
