Unsatisfied with Uber service

The driver Mbuso Ephraim went to the wrong address Then the trip was R33 00 When he came he is demanding R77 00 I gave him R50.00 he drove away with my change this amounts to theft Uber does nothing about this this is not the first time this happens you see a price on the screen when booking and when paying drivers want to fight with the passengers Uber needs to discipline drivers or prevent them from working for Uber the Uber company does nothing about these rogue workers
