Uber or Ola, always book ride on Cash Payment option. If anything happens because of Driver’s mistake, you have choice to Pay or not. In Post Paid service, they will automatically deduct the amount and its almost impossible to take refund back from Ola or Uber. OLA is worst, Uber is still better than Ola. In cash rides, u can also pay to drive by PayTM or Google Pay after completion of ride. So cash is best (tension free, pay & forget). Post Paid is big headache because refund policy is extremely difficult. Still Uber is better than OLA.
