Complaint about the Application and Service

On the morning of the 6th January 2018 I turned on my GPS location and logged into the Uber application. When I tried to select my current location, the application told me that I was outside the required travel area, and the app selected a random pickup location. I then cancelled the process and tried again. I tried a few times and the application did the same thing over and over again. Eventually I got a friend to drive me. When I had arrived at my destination, with my friends help, I received a call from an Uber driver asking me if I was going to meet him at the pickup location Uber had randomly selected for me. I informed him that I had not actually requested and confirmed the Uber ride as the app would not let me select my actual location. Later on in the morning I had a look at my email, where I receive all my Uber correspondences and I found that I had been charged a cancellation fee of R21 for the ride I did not request. I know it is only R21, but it is the principle I'm complaining about. I would like to be contacted and reimbursed for this amount.
