Uber India — Over charged my last ride

Yesterday i booked a cab from Tri-nagar new Delhi location to Sant Nagar ext. New Delhi at that time of booking my fare was showing 200 something after discount but when I drop to my destination my fare was showing 743 this is because cab driver take a long route because of that I got late to reach to my destination also. This is not my fault. kindly update the charges which are as shown while booking the cab.
