Overall good but drivers cancel and I am charged the fee

Overall good experience with uber - within the U.S. But also in Europe. One thing that needs improvement is ten fees they charge - the driver canceled when he was almost there putting me in a tough situation to find another ride and being late and I was charged the fee! It was refunded but as a favor to me with a scolding type email not to do it again. Are you serious? Or, now their time after they charge was moved to 2 minutes, that is also not right because the ETA is always wrong - if I have a choice between a taxi, uber or left ot another and I go with uber because of a 5 minute ETA, then after 6 minutes of waiting the ETA changes to 10 minutes because the driver decides to take another route - I have no choice but to find another way. I know they try to keep people from abusing it but they have to improve their app to charge when it truly the rider cancels for no reason. Also, the map needs improvements for directions - I am always picked up and dropped off on the wrong side of the street - its a busy 6 lane street and for me to cross and meet the uber requires going some walking, a red light and some more walking - sometimes that is hard to do when I have heavy bags, suitcases or bad weather.
