The problem with the app is that these days when we book the ride and driver is unable to comply to deliver us to our destination, we expect them to cancel our ride. But that doesn't happen normally and so after long time of waiting we have to cancel the ride. This results extra fee charge at our side charged by Uber which is seemingly unfair. Uber should urgently revise their mechanism. Uber in pakistan is getting unpopular these days because of unnecessary troubles being faced by customer.
