I have installed this app around 1 year ago to enjoy its services but my experience with it was not so good. First it will charge the same amount if it arrives before the expected time while in ola cabs if traffic is not there or it comes bit early, then your fare charges get reduced.
Many times they accept our booking even if they are very far from us because of that we have to wait long.
Moreover they also charges sometimes more what the actual fare show at booking time and we couldnt get our easily because same case has happened to me.
I have also not been satisfied with the behaviour of cab drivers, some of them talk rudely to us. Once when I was having my ride and I told the driver to play the song on cars speaker, he denied to me and he was like making some irrelevant reasons for this.
Thats all for my review
