Uber India — overcharged rs 315

Address:	Pune, Maharashtra
Website:	uber.com

Estimated fare was 415 and i travel on that route almost daily with uber. I was charged rs 729 for this trip, when checked with uber, they said gps error and will refund money. Today its more than 17 day but no refund yet. After 5th oct they stopped responding to app messages. I paid almost 315 rs extra which is not aa small amount. I want my refund.
I want o talk to customer care but there is no call back facility and no customer care no. To highlight issues. Really poor management of customer services.
I am still using uber because no other choice for me... Really not satisfied with the service. They have error in their system app customer service, why would i suffer, i just want my refund.
