I need to cancel a recent subscription that my son did accidentally

Hey Diala,

To cancel a subscription, go to settings > [your name] > subscriptions > click on the subscription to cancel > tap cancel. You will however still be charged for the first month/year/week, and it will not be possible to receive a refund.

Hope this helped.
