What laws govern commerce via apps?

There is a persistent myth that the app ecosystem operates in an unregulated environment.

Under the law, both are responsible. The platform and the partner supplier are part of the same consumer chain and are jointly liable. You can contact either one to demand an exchange or a refund.

Is it allowed to charge a service fee without prior notice?

No. All fees — whether for convenience, service, or shipping — must be clearly stated before payment confirmation. Any amount added without express authorization constitutes an abusive charge and must be refunded.

What should I do if I'm charged twice on the app?

Notify the platform's support team by attaching the statement or proof of the duplicate charge. If the refund is not processed quickly, contact your credit card company to formally dispute the charge.
