Cancel trip after 20 minutes

I would like to express my disgust at this mornings experience with uber. I requested the taxi just after 9.30 and waited for this driver. From the tracking you could see that my location and where the driver was going was completely different. After waiting 15 minutes I contacted this driver three times and each time he switched it to voice mail. Completely useless and utterly unprofessional. Then I received a notice that the idiotic driver had to cancel my trip. And you still ****en charged me for that cancelled trip. Yet my time was wasted and as a result I am now late for work. Uber has disappointed me completely, the driver had no common decency to even phone me to find out where i was standing waiting for him.
