Uber prejudices their driver

I am beyond irritate with Uber. I ordered an Uber yesterday to take me to my doctor's appointment at Milnerton MediClinic. The driver arrived and I could see all his credentials on my app. When he wanted to initiate the trip on his phone, however, he couldn't get it to give him the 'Go' button and he had no option but to cancel the trip on his app. He did however take me to Milnerton. When I got home, I messaged Uber as I would like to pay for my trip and ensure that the driver is paid, which is only right as he did make the trip. What a damn runaround!!! 7 senseless replies later, I am still no closer to resolving this problem. If they will just give me the guy's details, I can pay him for the trip, which is only right as he used his time and petrol. It's like speaking to a machine, which I'm sure it is as the replies look like they are computer generated and HIGHLY IRRITATING!! I won't be using Uber again if this is the way they choose to do business and if this is the way that they treat their poor drivers, who get the short end of the stick in any event!!!
