I was staying in glasgow and use this site to organise a taxi for a work appointment the next day. The details of the taxi company they said had been booked for me were invalid. I called taxibooker back who then said they couldn't help and would refund my money (it wasn't much, bit I work hard for my money and don't see why they should get any of it for NOT providing a service) - over a week later, despite several calls, I'm still waiting.
