Ola Cabs / Ani Technologies — ola car booking cancelled by the driver and charges levied to me in the next ride

I booked a ola car to go to mirley eye care centre near bharathi nagar police station st. Jhons road from 8th cross, dinnur, r. T. Nagar. The cab driver prabhu (White micra ka51d9245 - otp7379) informed me that he is near r. T. Nagar police station. I gave him the directions how to come to my place. Despite calling him & giving him directions he went to poornima hospital which is hardly 1 furlong from pickup point. He kept on asking how far it is from that place and cancelled on his own. Since it was showing the pick up car has arrived in my android cell phone and as he has cancelled on his own the call the charges of rs.50/- were levied and added to me in the next journey and put to very hardship to me as i had to reach the eye care centre urgently. Please therefore recover the amount and refund it to me.
