OLA is a taxi service I do not use but I listen about it. This service is provided to help to go anywhere this service is I think work all over India. I think it is helpful for all. Sometimes any person want to go anywhere but there is no transport service then we call OLA cab then they give them. I think it is trustable its drivers are registered with OLA. If any find any problem then contact to OLA complain. I think they will solve there problem.
