Uber India — driver totally unprofessional, please take action

Yesterday morning, 04/10/2019, i booked a cab from greater noida to lajpat nagar, it showed 4 minutes waiting, the car took a route which was going opposite from the pick up point. I called after 10 minutes because the car, at a point, was not moving. He said he was at the petrol pump and was almost done. I called 4 times in the next 10 minutes because i was getting late at that point. Finally he stopped picking up the call and the car disappeared. Somehow he cancelled, but i could not see the notification, neither trace of his trip...
Bottom line, i reached my work appointment half an hour late because of this person!
Thank you
