Uber India — I've been wrongfully charged!!!!

What happened -

- I book an Uber from IGI Airport T3 to get dropped in Dwarka...
- The driver calls me to check where I need to be dropped.
- I tell him I need to go to Dwarka
- He tells me he has reached the pick-up point and drops the call.
- I see the pop-up that the trip has finished and have been charged a sum of INR 380.60 without even being picked-up!!!
- There was no way of contacting the driver!
- And I could not book another cab using the UBER app as it asks me to pay the amount before booking another ride!! Pay for WHAT exactly?!!
- I had to resort to a Pre-Paid Taxi service from the airport eventually!
