I end up paying Rs19/km average for 12km. I booked Ola Mini cab on 13th March 2015 and used it between 1930: 2030hrs. The bill came as Rs229/- for 12.1km. Yes, they informed me that they will charge me 1.3 as peak time charge and ended up paying Rs19/km.
First of all they will mention the peak time charge only on the booking time so that all the time is peak time for them. Then waiting charges additional. No other provider is charging like this. I used it as I had no option left with and that is the point this OLA team get to milk the clients.
If it was Meru Genie, the charge would have been around Rs165/- the max. So if you have any other option NEVER hire OLA cabs and I recommend MERU Cabs.
