If you encounter any payment issues (overcharge, double charge etc.), you can request a refund directly at the till at the outlet where you transacted. The till operators will be able to process a refund directly through your Yoyo app.
If the cashier has agreed to give you a refund, open up your payment tile and scan the QR code against the Yoyo accepting device at the till. Your refund will come through as Yoyo credit.
Always feel free to email us at email@example.com.
