Subscriptions
How do I cancel?
On your iPhone, open Settings › Apple Account › Subscriptions › Big Why, at least 24 hours before the trial or the current period ends. Or, in Big Why, Settings › Subscription › Manage subscription. Deleting the app does not cancel it.
I paid but talking is still locked.
In Big Why, Settings › Subscription › Restore purchases. If that does not help, write to us with the email you signed in with.
Can I get a refund?
Refunds are handled by Apple at reportaproblem.apple.com.
