The feedback system of Uber is very poor. Even if the drivers do not come to the location for pick up or do not follow the instructions there's no proper way to register complaints. Though the fault is on the driver's side Uber charges cancellation fees from the customers. Because of this the drivers get away with anything. Many Uber drivers are rude and they misbehave with the customers. Just waiving the cancellation fee is not enough. Uber must take strict action against such drivers.
