Uber India — Overcharging although initial charge was shown

Address:

New Delhi, Delhi, 110049

I booked an uber to gulmohar park to go to central park 1, golf course road gurgaon. The fare on my phone was 153.99 but when my assistant who went in the car reached destination the driver demanded much more and showed his phone.
This is not the first time that the drivers are overcharging and i want to know why it is happening.
