Findmy kids app

I download this app with intention to trial it. When I trialed it realised it doesn’t work without connectivity so if my kids aren’t on wifi or have no data - there is no way of the app being useful. I had not signed up for the actual paid subscription nor granted consent for them to sign up. By the time I was deleting the app I check under my subscriptions and I see it’s auto renewed and charged me. At this point they refuse to reimburse my money and are bullying me into the subscription! Do not even trial this app as that is you automatically being ****med into the formal subscription!!!
