Our deepest apologies that the driver had not done so. Our drivers have been told that the final metered fare should be the one reflected on the Mobile Data Terminal (MDT) and not the meter. The metered fare displayed on the MDT would have taken into account the promo code discount. Please make a report via our feedback form below; you may click on 'Submit a feedback form', select the 'Promo Code' category, and provide us with your booking trip details so that we can conduct an investigation into the matter. Alternatively, you may contact our Customer Service Centre at 6552 4525.
