I purchased the ticket online for a 4:25am departure. I thought the confirmation email would work on my phone with the bar code on it.  The driver told me to print it out to get on board, but at 4am, there is no way I can print it at the hotel.  So I have to pay the driver again to go to the airport. I called their customer service and they asked me to request refund when I get back home. But so far, no one answers my request through email or online request form.
