I have been a frequent user of Ola Cabs. It was my preferred radio cab company as 1) Meru was often acted very pricey and wouldnt come for short durations 2) Uber required credit card information.
However during my frequent interactions with Ola, their customer care, their drivers, their offers, I began to realise that they are bringing out offers that are CHEATING customers. Lot of their offers are just meant to attract customers and the 50% off offers are often fraud.
