One of the best cabs out there. I have been using their services for the past 1 year. Their app is also quite easy to navigate on. One of the best things is that they have plenty of cabs, so there are very few "no cab available" moment with Ola.
Their Drivers are also professional and their support team is the best. Things are bound to go wrong, but there should be a team in place to fix things up. I have had few bad experiences, but they were prompt in their action. Love their services. And now they even have the cashless ride option which is quite amazing.
