Uber India — driver took cash payment for non-cash ride

I booked a cab for my family but i was not riding. I had put non-cash payment for the ride. The cab driver asked for cash from my family and took cash amount for the ride. Later i came to know about it and informed uber about it. Uber support said that they can't do anything about it and i have to pay for the ride again since it was the non-cash ride. Uber did nothing to help me out here. I had to pay for the ride again.
