Address:

I booked ola call taxi to move from koyambedu to mugappair.in this ola charged cancellation fees : rs.50 with my bill. I called and asked ola customer care. Their feedback is on 9th sep 17 trip cancellation by myself.
Actually on that day i plan to go tirupathi. I booked ola. Initially accepted by ola driver and cancelled by himself. After that i booked fasttrack & used.
Ola : cancellation done by ola driver, fine received from customer. What a service?
Today morning also 2 drivers accepted booking and cancelled.
I need proper compensation for unwanted frustration to me. I plan to publish in all public websites
