Uber Chennai, India — driver is miss-use the trip

Address: Chennai, Tamil Nadu, 600114

I have booked the cab early morning (2.00 am to 2.15 am) to catch the flight to singapore. From pazhavanthangal to chennai international airport drop. The driver details arrived to my mobile @2.00 am sharp, and the driver also came down to pickup location and suddenly he cancelled the trip when he was in pickup location. I saw the message and called him he says that it is automatically cancelled due to time laps. But he told me lie and he pick up the same trip with different amount. Uber shows the amount when i was booked it is (190rs to 226 rs) but he charged 300. Because he is demanding with my father on that time. See my father 72 years old and driver is creating last minute tension to my father, this is what happened. So please tell me the solution or take action against him. Other wise i will share the news to social media.
