Uber *****s from clients or app not working properly

Uber is a biggest **** company ever, drivers make sure you Wright every trip down,I have definitive proof Uber wallet with cash unstable eg 200 cash trip 50 rand cancel 10 rand so two trips 10 rand equals 20 rand 200 minus 20 supposed to be 180 what this messed up app does is take 120 50 for two trips and 20 for drivers cancelation when look at history says 2 trips for 10 rand but no 50 but still the two 50 rand canceled trips not shown in history but it still took it off Uber cash balance these people are sick. Terrible Terrible experience
