Ola offers a low cost, I agree with it. I would like to mention the pros and cons below.
Pros:
1. Quick booking via OLA app
2. Moderate cost
3. Good user interaction
4. Nice offers
Cons:
1. Problems with advance booking
2. Booking cant be done via call
3. Cancellation has to be done by us
4. Peak hour charges are too high
5. Many trip requests are ignored by drivers
I have faced issues with the opeartor many times like the ones mentioned above. The app wass not working properly when I needed. the other time all cabs were double charging due to peak hours rates. And they also dont provide intercity transportation.
