Uber is a terrible app that crashes all the time due to 'technical issues'. I've also found that they have little to no customer service as they don't seem to care about making up for their mistakes which cause delays and inconveniences for their customers. I'm very unhappy with my experience as I just waited for a half hour, in the cold, in the middle of the night at the airport for them and I was told that their was nothing they could do to resolve my issue. *Two thumbs down
