It is so annoying that drivers keeps on cancelling after calling and asking where do I want to go, especially when I'm rushing. This is the worst system, one driver is using ola, uber and other apps and checking which one is the best option, accepting, calling them and when the price is not right for them, they cancelling, it wastes so much time, a perso who's rushing can never depend on your app, in other words, your app isn't reliable, fix the system please.
