Uber — uber ride - forced cancellation

I booked a cab on uber using my number [protected] on 12th november, 2019 from igi airport, delhi. I could get hold of the driver after 10 minutes, and then the driver told me to cancel the ride myself because he had an issue with his car. When i tried cancelling, i got a notification that i will be partially charged for the ride anyway. Now this is extremely unfair, since i should not be asked to pay for a ride when it's not my fault that it is being cancelled. I told the cab driver to cancel it himself, but he refuses to, and is now hassling me to cancel it.

This has been a very disappointing experience with this app.
