Uber India — demand high price instead of estimated

Hello
My self rinku rajai. Yesterday i used uber first time. I booked cab but it was cancelled automatically... After that i book the cab agai from uber. It saw estimated fair 164 clearlly. Transaction id is as follow. T5e133a8e62cd0051f0cd2b00. 24 aug 2017, 01:22 pm. I travell trough that cab & reached destination confortably. At that time driver demand 275 ₹ insted of 164₹ may be it is 5 to 10₹ variation i can understand but it was huge difference between estimated and real fair. I argued with the driver but he did not want to understand the thing. So thats why i have to pay 275₹ at that time. Now i request you to refund difference money. Otherwise i have to take legal action. I m telling you second time first booking was not cancelled by me & also i don't understand what was the reason for charge more money then estimated.
Please justify...
