Unhelpful
i accidentally used a grab voucher code on my ride and i couldn’t even cancel it, by then by driver had already accepted my ride and then i called grabcentre and they couldnt do anything about it. there should be a button for cancelling your voucher code or at least a confirmation button. the fact that grab couldnt do about this issue is upsetting literally all you have to do is refund me a voucher lol.
