Ola Cabs / Ani Technologies — ola driver cancellations

I am questioning whether ola cabs in delhi is a legitimate service. After their excellent service in dehradun i was astounded by the poor service i received in delhi. I needed a numer of rides over several days and half of them were cancelled by the drivers! Four in total. It seemed obvious that;
* the drivers did not understand the ola navigation technology
* the drivers did not know the areas they operate in
* the drivers were too lazy
* the ola navigation system failed when bandwidth dipped.
Furthermore there is no customer support when these issues go awry.
I guarantee i wasted 4 hours over 2 days due to driver and ola incompetence. I am switching to uber and local cab drivers for future local transport.
