Uber India — Frequency cancellation by cab drivers while booking cabs

Whenever i try to book cabs most of the times cab drivers cancels the trip which cause so much delay in going anywhere. Sometimes cab driver cancels the trip when 1 minute left to arrive and the worst thing is that they first ask where are you going and then cancel the trips. And sometimes they dont cancel the trip but they dont even move their cabs nor they receive phone calls out of which we have to cancel cabs after waiting 15 to 20 minutes then we are charged unnecessary cancellation charges. This is so unfair which needs to be monitored seriously.
