Wrong drop-off location

I chose 1 Bradfield Dr, Sandton but was dropped at 1 Bradfield Dr, Johannesburg. Upon realising that I was at the wrong location, i wanted the driver to drop me off in 1 Bradfield Dr, Sandton and started another trip, clicked on 1 Bradfield Dr, Sandton and the app showed me that I had arrived whilst I was in 1 Bradfield Dr, Johannesburg. I had to search the nearest place to 1 Bradfield Dr, Sandton which was montecasino and choose the route. I was charged for both trips regardless of the Uber App’s mistake. Regardless of Uber’s mistake, they refused to reimburse me
