Uber India — uber cab/ outstanding charges applied for no reason

Address:	Mumbai City, Maharashtra, 400063
Website:	Uber app

I had booked a cab today around 12:08 and i was tracking the cab on app. At 12:15 driver cancelled my request and i was charged cancellation charges. The driver did not even come to my location and i waiting exactly at my pickup location. When driver has cancelled my trip why am i charged money. This is second time i am facing this issue.
Earlier i was waiting in my pick up location for almost 1 hour and driver was not reachable on phone also. So i took another means of transportation. When i reached my destination i received a call from uber driver and i cancelled the request and again cancellation charges.
I feel like we should not even rely on uber services
