Facetune Free Trial Cancellation Fails to Stop Unauthorized Apple Store Charge

I downloaded the Facetune application on my iPhone as a free trial and cancelled my subscription on the very same day before the trial period ended. Despite this, $29 was deducted from my bank account today under the label "Apple Payment," and when I spoke with my bank, I was informed that this transaction belonged to the Facetune app.

I do not accept paying for a subscription that I cancelled during the free trial period. I am retired, and $29 is a very significant amount of money for me. When I called Apple Support, I was told the transaction would be reviewed, but as of now, the money deducted from my account has not been refunded.

For this charge, which I believe is incorrect and unfair, I demand that the $29 for the Facetune subscription be refunded to my bank account in full as soon as possible.
