Poor service

The service was very poor this evening. They changed my first driver to a second driver. Charged me for the ride. I contacted first and second driver to ask where they were no response after waiting for more than 30 min. Than I had no choice to cancel second driver. Requested 3rd driver of whichshe also never responded after sending messages. Called her a couple of times than she answer only to tel me her battery is flat and she got lost. Yet Uber charges me for all 3 rides that never happened. Poor poor service from these Uber drivers.
