I travelled in a Tata Indica the notification states that hiring a small cab (D class - vehicle costing below ₹* lakh) will cost ₹ ** for the first * km. For subsequent km, the aggregators can charge a minimum fare of ₹ ** and max of ₹**. For C class (vehicles costing between ₹ * and ** lakh), the first * km cost will be ₹ **. For subsequent km, a maximum rate of ₹ ** and minimum of ₹ ** will be applicable.) So the max price in case of C class would be around Rs *** & not more. I am overcharged by Uber in normal fair by Rs **** /-
*. I have written a total of ** emails & escalation emails to Uber CEO & twitter escalation without any response. I have written mail on *th May it has been * year ** days without any resolution
Basically uber showed me Rs *** before the trip started & charged me Rs **** post the trip. Secondly, the driver threatened me to leave me midway on my way to the airport & the amount of mental agony. I went through is unacceptable & the fraud charges by uber are unbearable.
