Getcontact Free Trial Turned Into Paid Subscription Automatically

I used the 3-day free trial of the Getcontact app on my Android phone. However, about 10 minutes after the trial period ended, ₺160 was charged to my account through Google Play without my consent. I did not use any paid features or additional services under the paid subscription — I only took advantage of the free trial period.

I immediately canceled the subscription after noticing the charge, and I have not yet submitted a refund request. My registered phone number with the app is 0533*******78.

I request a full refund of the ₺160 that was charged without authorization, as the free trial automatically converted into a paid plan without my approval or usage.
