Uber charges for services not rendered to me

On the 23rd September I attempted to use Uber connect for a parcel I needed from dragon city, the driver indicated that he had arrived but didn't answer his call, a fee of r104 was charged to my card, I wrote to Uber support to make them aware that I was charged R104 for a service that I was not rendered to by the driver. I was refunded R20 which does not make sense because I paid a lot of money for a driver that did not render a service. This evening I requested a ride home, from Rivonia village. On the app it indicated that the driver was 1 minute away, while still waiting for the driver the app indicated that I was on my way, I canceled the trip because I was not in the car and wrote to Uber that I canceled because I was not in the car, the support system at Uber insists that I was in the car when I was not. I was charged R32 for the cancelation. This all does not make sense. The app just keeps insisting that you used the driver even when you did not. I ended up requesting from another service provider because I was not in the car
