Ola Cabs — Ola cabs cancelled my booking themselves and refusing to refund the amount

I had booked the Ola cabs on December 19, 2015 to travel to railway station. The booking was confirmed and I was waiting for the cab but at the last moment they themselves cancelled the booking. Because of that I had to drive my own vehicle to railway station and pay huge parking charges. I need Ola cabs to pay the penalty by reimbursing the amount what I have paid for parking and also, refund the Ola money which I had reserved to use their service.
