I was planning to use it for both round trips this time.
The driver who dropped me off when I arrived told me that when I left, I would pick up at the place where I dropped off my outbound flight 3 hours before the departure time of the return flight.
No matter how long I waited at the place on the day, I didn't show up and there was no response to my post to the inquiry. I also tried to call from the information (where I could see the pick-up place) but nobody answered or even contacted me.
I ended up waiting more than 30 minutes , I posted and phoned many times, but it was pear pebbles, so I gave up and quickly caught a taxi, just in time.
The result was a boarding that cost $45$ including tips, was over budget and had no time to spare.
As a side note, I didn't even get any response to the question section I sent when I was informed that there wasn't enough information about my departure. Maybe this was the cause. There is no denying that the contact details were wrong in the first place, and I can't tell if VIP or TripAdvisor were to blame.
