The App is useless

<p>Today I attempted to get an Uber; I had more than a year ago signed up. My credit card details have since changed. The app would not allow me to pay cash and rejected all attempts to do so. I had to call a friend who quickly downloaded the app and ordered an uber for me. She did not enter her credit card details and used the cash option. This evening I attempted to change my details; after numerous efforts I changed the details. When Intried it out, it would not give me a price, but the taxi was ordered. The app told me the driver would tell me how much it cost at the end of the trip. I was once again not allowed to choose the cash option. I then cancelled the trip and was charged R 25 which I have since been told has been refunded. At the same time, the friend who had helped me earlier 'ordered' a taxi, was given a price and allowed to pay cash. How does this work? I want to pay cash. The problem is that when encountering difficulties there is no one to contact.</p>
