Ola Cabs / Ani Technologies — Charges for the ride

Today, the 1st of december, 2016, i had placed a booking for ola micro, the crn no. being[protected] for my travel from goregaon to j. b. nagar, andheri. i was shocked when told that the fare to be paid was rs.317/-. while booking the cab it was not informed that higher price will be charged. on reaching home and on going through my email, i found that rs.160.56 has been charged extra, and the reason for the excess fare given was "fares are higher than usual when the demand goes up. your total fare was calculated as per the revised rate card".
Had this information been given at the time of booking we would not have gone ahead with the booking. we were caught unawares. for our return ride i paid only rs.147/-.
Its my sincere request to inform the clients of these fare changes at the time of booking itself. i also request you to please refund the excess amount charged. expecting a line in reply
