Uber India — Delay in arriving and driver cancelled the trip.

I confirmed a trip to UCO Bank, Jessore Road, near Kalindi Bus Stand, Lake Town, Kolkata from Action area 3, Newtown, Kolkata. The driver was not moving a littlebit. Therefore, I phone called the driver 3 times, but everytime he was cutting the call. Neither he received the call nor he moved. I was getting late so I came in front of Pride Plaza hotel but I didn't cancel the trip. The driver got changed. The next driver phone called me. I told about the previous driver's negligence. Then he asked me where I was, I told that I was in front of Pride Plaza hotel. But after sometime, the driver only cancelled the trip, but it's showing that I have to give Rs. 20.52 extra as cancellation fee though I didn't cancel. This is not justified.
