Uber India — overcharging and blackmailed by driver

I booked a cab at bhubaneshwar airport at about 11.30 pm on 19/1/2018 for going to landmark hotel, jatni which is about 26 kms from the airport. The fare shown was rs. 272/- i was charged an amount of rs. 585/- through paytm. Over and above this the cab driver took an additional rs.400/- in cash to which i was forced to agree as the cab driver refused to take me to my destination. I had no other option but to pay. When i complained to uber india they have refused to refund the excess amount saying that my complaint is not maintainable
