Incorrect charges on my bank account

Yesterday I booked trips on the app. The 1st trip showed that it would cost R28, it cost R32 instead, no problem but instead it took R100 from my BANK account, the second trip the driver said they are at the location, the guy was not even where i requested for my parents, i called him spoke to him and he acknowledged he is not at the correct location, he was a street away, a few minutes later he still hadn’t moved to the correct location, instead it said free waiting time expired. I tried contacting him with no response from his side. I then cancelled the trip and on the app it said you guys charged me R19 (still unfair because he **** and it clearly showed he was not at the requested location). He was at the wrong location and yet on your app I was still charged R19 however on MY Bank Account the full R146 from the trip was deducted . I requested another ride and was charged R151 and the gentleman picked my parents up. How is it that I am charged R100 on my bank account for a R32 trip and R146 for a trip that did not take place. I am not getting any help form your support people on your app, it doesn't even show the supposed R32 on my bank account at all
