Deficiency of services by taxi stand owner

I had booked a taxi to take my son to IGI airport to catch a flight to Doha. After confirming that a taxi would be sent on time, the taxi stand owner kept putting us off with some excuse or the other and then stopped answerimg our phone calls. By the time we could arrange for another taxi it was pretty late and my son missed his flight. He had to purchase another ticket costing around Rs. 25,000. I would like to take the taxi stand owner to consumer court. Kindly advise.
