FamRadar Subscription Not Showing in Google Play – Refund & Cancel

I am using the FamRadar family plan, which I started as a trial through the Google Play Store. Although I have already uninstalled the application, money continues to be withdrawn from my bank account. So far, I have been charged €51 on 15 March, another amount on 20 April, and €14 on 13 July. When I checked my Google Play account settings to cancel the subscription, I could not see any active FamRadar subscription there, so I was unable to stop these withdrawals. I request that my FamRadar family plan subscription be completely cancelled and that no further charges be made. In addition, I kindly ask for a refund of the amounts that were charged to me despite uninstalling the app and not being able to see or manage the subscription.
