CamScanner Charged 599 TL After Canceling Free Trial On Google Play

I started the 3-day free trial of the CamScanner app and canceled my subscription immediately afterward. Despite this, today I discovered that ₺599 was withdrawn from my account through Google Play.

This is completely unfair and misleading. If a subscription is canceled before the trial ends, no charge should occur. I never authorized this payment beyond the trial, and yet the money was taken from my account.

I have not yet contacted customer service, but I am requesting an immediate refund of the ₺599 that was wrongfully charged. This problem needs to be resolved quickly, and I also expect CamScanner and Google Play to prevent such misleading billing practices in the future.
