I just returned from a one week trip to Delhi. After using both Uber and Ola, I conclude that OLA IS RUN BY CROOKS. Every time I used Ola, the fare was anywhere from two to three times more than what I paid with Uber. For the same distance, Ola charged me Rs. 180 vs. Rs.100 by Uber; for another destination I had to pay Rs. 480 instead of Rs. 200. For the airport, I had to pay over Rs. 1, 000 instead of Rs. 300.
My advice: STAY AWAY FROM OLA. THEY ARE THIEVES.
