Customer Unfairly Charged for No Service!!!

I requested a ride with Uber at around 12 pm today so that I could meet with a client. The Uber app showed that the driver was 1 minute away, however after 5 minutes there was still no driver. I kept phoning the driver "Basil" to find out where he was, however he did not answer any of my calls. I thereafter received a notification on my app that the driver had cancelled the trip and that I was liable to pay R 25.00 for a trip that never took place. This Uber driver was unprofessional and rude to not answer any of my calls. This incident with this Uber driver had inconvenienced me greatly, as I had to cancel my meeting with my client due to not having any transport. The R 25.00 bill that was charged to me must be waivered with immediate effect. The Uber driver cancelled the trip without any effort to contact me (the passenger), and therefore I will not be paying any fees for non delivery of services. Uber should consider employing drivers that are more professional and considerate to their passengers and Uber should not charge passengers for the wrongs that their drivers commit.
