cancellation overcharged and Exploitations of riders

They are exploiting South Africans, The Government must impose some heavy task on them and control their fairs and the percentage they take from drivers, I booked a trip of 6km at the cost of 38, rands, due to log wait i cancel after the driver could not move, i requested another and it was confirmed for 38,00 when i arrived on to see thee driver charged me 64.00, when i called Uber they told me i was charged 26.00 for cancellation. is this not *****ing ?
