I'd say that this is explicitly meant as a punishment to disincentivize such actions. Completely canceling the transaction just undoes the damage, and only if it places zero burden on the consumer - no shipping costs nor effort, which is unlikely.

This may come out as a 'double refund', but in generally accepted practice, paying triple of the dishonestly earned amount is also often considered an reasonable measure just as a penalty.

Otherwise if half of the cheated consumers complain and get their money back, and half don't notice it, then it's still a net win for a shady company and an incentive to continue such activities, contrary to the explicit goal of this legislation.
