[Resolved]  Meru Cabs — Cab did not turn up

I had booked meru cab on 14th of january 2016 to catch a train at 11pm.I got the booking confirmation and 20 minutes before the scheduled departure i was messaged the details of the driver.After five minutes of receiving the message i was contacted by the driver and he said he cant come.I was aghast as at that time i could not have got any other conveyance especially for females travelling alone.So called the meru cabs again and they said another cab would be arranged in 15 minutes and again i was messaged the details of driver.the driver called up asked about pick up location but never turned up..when meru cabs was again contacted they expressed their helplessness.Had they told me in the evening iteslf i would have made some other arrangement.But these shameless people would never understand what it is like missing your family functions and missing trains.It had to go through mental stress and financial loss to which they were obviously indifferent.Can anybody tell me what would be the procedure to take legal action against them?
