Uber India — over charging for the car ride

Address:

Chennai, Tamil Nadu, 600059

My name is muralikrishnan and i took a uber ride from villivakkam to pallavaram on chennai. The initial charge suggested to me in uber was 411 rupees. On completion of the ride i was charged 577 rupees. When i contacted uber i was told that the drop location was changed and the route i took was changed too. But the drop location was the same and we took the shortest route. I asked details of the extra distance and time that the actual ride incurred more than the initial estimate and uber is not answering those questions. I need a proper explanation from uber on it
