Uber India — not pick up by the driver

I booked a cab at new delhi metro station on 1/10/2017. Uber confirmed my booking and display the detailed on uber app. I wait there 5 min as time displayed by uber app but there was no uber car and then i saw the car location it was just nearby me but it was not moving toward me. I wait there almost 30 min but car was not moving and driver no was not reachable. You uber guys dont thinks about your customer time value. It was very bad experience to me with uber.
Driver name was nitesh and his car was wagaonr dl1rtb8108.
