Shocking UBER driver behavior causing serious financial set-back

On 01/11/2021, at 13h00, I ordered an UBER for my guests to Park Station, Jhb for 16h30pm. They had a a bus destined for Upington at 18h00pm. At 14h30pm, an amount of R 395.00 was debited from my credit card and a driver assigned (his name is Owen). I was live tracking him on the UBER app from 16h00pm to ensure he will be able to see us when he arrives at 16h30pm. However, when he had still not arrived at 16h45pm, I wanted to track him and saw to my surprise HE cancelled the the trip! I hastily ordered an immediate UBER when a new driver accepted at 16h50 pm and picked up my guests at 17h10pm (his name was Casper). He tried his utmost best to get my guests to their destination on time but he unfortunately failed - they therefore missed their bus and we had to collect them at 19h30 pm at Park Station. To my utmost disgust, i saw that I was charged R 405.00 for this second UBER. Now, I want UBER to understand and also make sure that this is utterly disgusting and shocking behavior and I will not tolerate the fact that I am charged double for something I did not cause. As a matter of fact, I want to hold the initial driver ***en) responsible for not only this additional R 405.00 that the 2nd driver (Casper) deserved, but also the R 780.00 my guests has lost by now having to get another ticket, also due to no fault of their own. This is very shocking behavior by an UBER driver and I need to know that I will be refunded immediately for the additional charge, and action is taken against the unprofessional driver.
