Unauthorized Charges From FamRadar Trial

I am using the FamRadar iOS app and have recently noticed repeated unauthorized charges linked to this application. In the last month, a total of $85.21 has been withdrawn from my US checking account via debit card without my clear consent or awareness that I had an active, ongoing subscription. Specifically, there were three separate charges on March 8th, one charge on March 9th, and another charge on April 9th, all debited directly from my bank account. When I tried to investigate, I was not able to find any official FamRadar website or functioning customer support channel, which makes the situation even more concerning and makes it impossible for me to resolve the issue directly with the provider. In addition, I am unable to find a way to remove or cancel the FamRadar subscription from my account, so I cannot stop potential future withdrawals myself. This leaves me feeling unprotected against further unauthorized charges. I request at minimum the immediate stopping of any future charges related to FamRadar and the complete cancellation of any active subscription tied to my account. Ideally, I also ask for a full refund of the $85.21 that has been taken so far, since I did not knowingly agree to these repeated charges and have no way to contact the company.
