FamRadar Charged Me After Three-Day Trial Without Consent, Need Refund

I used the FamRadar application on my Android phone, where I only requested a three‑day trial version. Despite this, around today approximately 10 000 HUF was charged to my account, and afterwards they tried to charge me again, but the payment could not be completed because of a restriction on the account. I did not intend to purchase any paid subscription beyond the three‑day trial and I do not accept these extra charges and further attempts to charge my card. I request that my FamRadar subscription be cancelled immediately, my account and all my personal data stored in your system be deleted, and that the collected amount of approximately 10 000 HUF be refunded to my account.
