Sorry to hear that it isnt going well. We used the service simply to make things easier for my wife as she had a long and difficult journey into Manila from Cavite and this was perceived as a way of making the whole trip in a bit simpler / comfortable. It worked in our case. We were also able to get an appointment within 3 days. But if we so chose then 24 hours notice was possible. I spoke to the woman myself and she was very good with me.
I can remember exactly how the process went now but yes, once they have sent you the booking email, all you have to do is print it and take a copy with you to the appointment, along with the money.
