Uber advertises their prices, however once I finish the ride, I find I have been charged an average of $10-$15 more in a "booking fee", "wait time" fee, "airport drop off and surcharges". I prefer knowing upfront what the costs are. Secondly, the only way to communicate is through their APP - no humans, no emails, and if an issue is not listed, there is no way to report it. PS. Donwloaded my bill, but this system is not accepting pdf's or png's -?
