Trial subscriptions usually become paid subscriptions if you do not cancel the trial 24 hours before the trial ends. By not canceling the trial, you are authorizing Apple to charge you for the paid subscription.
The trial for Verevio was three days. To avoid it becoming a paid subscription, you needed to cancel it before the end of the 2nd day.
