I Demand Refund for Extra Charge on Yazio Subscription

I downloaded the Yazio app from the App Store and made a payment using my card. The app was supposed to charge $1, but I noticed that $9 was deducted from my account instead. The transaction took place on March 31 at 2:33 PM.
I believe the extra $8 charge is an error. I have not yet contacted either Yazio or the App Store regarding this issue. I request that the overcharged $8 be refunded to my card as soon as possible.
