I booked my first ride last month at Ola from shahadra to Ghaziabad, I checked the estimate fare charge before ride this shows that around 196rs. but after ride the driver shown me 296rs bill. He tell me that the 100rs is the state border tax.
I got dissapointed but otherwise you take a ride in Delhi you will feel better than my first ride. So I suggest you that before taking you first ride please read their terms and conditions
