Google One Renews Subscription Early and Charges Account Without Permission

My Google One subscription was originally scheduled to renew on August 21, but it was renewed early on August 20, and approximately $1 was charged to my account. Because of this, I went into the subscriptions section on Google Play on August 20 and confirmed the cancellation to stop the renewal. Even though the screen explicitly stated that the subscription was canceled and would end on August 21, I was still charged the fee.

I was unfairly inconvenienced because this transaction occurred entirely against my wishes as an early renewal. Despite reaching out to Google Support, I received no assistance, and no refund was provided. Because this charge is clearly a mistake, I demand that the deducted amount of approximately $1 be fully refunded to my bank account as soon as possible, and that no further fees be charged for this subscription.
