The child poked something on the phone and accidentally signed up for a trial subscription for 7 days, after the trial subscription will be extended for a year. I couldn't cancel the subscription 24 hours before the end because I didn't see it. As a result, I am now unable to update the payment system to pay for music and cannot cancel this subscription.
