Uber India — fare & without navigation

Address:	Pune, Maharashtra, 411021
Website:	www.uber.com

Dear sir/ madam,
I m chakraborty, i traveled uber from gulmarg co op housing society baner to ramkrishna math, pune by tata indigo bearing registration no mh 14 fc 2171.
The driver was unprofessional don't follow the gps navigation even in capable to drive in pune city. My estimated price was 398 finally the driver lost the way, i was decided to left the car in dagdu seth ganpati temple my final price was 546. The driver not turned on the gps navigation.
If a driver did not follow any gps navigation why should the customer bare the execess amount? Even i m also from a service industry. Is this the way to deal with the customers?
I need to revert back soon, if not i will take further action against uber.
Thanks & regards
D chakraborty
