I had the worst experience recently with ola cab.
I had to travel Long distance with ola form banglore to Ooty, inspite of pre booking they cancelled on me at 7 am saying I didn't take call. The driver gave me just one call that too at 6 am(I had booked for 7am) and cancelled the booking rite away.
Then after that I booked another and they urgently arranged another cab, this driver was most rude all the while and kept threatening to get me down in middle of the way if I said anything about the bad condition of the car. Yes the car had mosquito, dust layers and windows were jammed too. This is the kind of quality #ola provides to you when you pay for a prime car
Then the driver unfortunately fell really sick but refused to admit it in fear of loosing the ride back with us, so much so he had to go to hospital and be admitted for a night( kept saying he is healthy to go back).
We tried to get some other cab and cancelled with ola, but the cab driver made a gang with other drivers at resort(literally threatened us 3 woman) and we had to use the same cab on way back(note- drives still had I-v line on his hand and ola failed to book me any other ride, so I had to go with the same guy "unofficially ")
The most unsafe experience of life coming down from steepest Nilgiri mountains and driver puking all through he way.
Then I paid the rest of amount to him in cash as I reached. Ola now has marked me that I have pending amount(which I paId to driver in cash, and I can't use ola since a month) have made several complaints but no use. In city like banglore you can't do without cabs but no help from ola.
Conclusion
Don't book ola for long distance
Never pay drivers in cash
Use uber
