I was using OLA and now I decided not to use anymore. I feel OLA lost huge money by giving some bull* perks to driver and now they are trying to earn it back from innocent customer. Their pricing model has changed and now they change 1.5x to 1.6x of total charge along with waiting time(in signal too).
So I advise you all to stop using OLA and go back to auto(or any other taxi aggregator)
