Ola Cabs — Over charge & cancellation policy

Address:	560016

If the total travel charge is 135 rs. Why the driver charged 185.00 rs?? Ola is now cheating people. This is the 1st time i am facing these kind of issues with ola. Today i travelled by ola & booked ola for my wife as well. But with these kind of experience i don’t prefer travelling by ola in future.
1) the first driver was 8 to 9 km away from me & said he will arrive in 30 min. So i said i will cancel the ride. Since he did not know that the horamavu railway construction is going on & he was on the other side of the railway gate i cancelled the ride. & i did not get any message on my phone after i travelled by ola. So how am i to know the charge?
