OVERCHARGING ON MY CARD

I’m very disappointed with the integrity of the Uber drivers. I’ve created a family account and on two occasions over the past week have been overcharged on my card. First a driver that had to pick up my son took another call, but did not cancel my son’s trip. We were charged R54 for that trip. We reported it, but the charge to my card still has to be reversed. Last night my son requested a ride. The driver cancelled and according to the app the charge was R25. The charge to my card was R85. To add insult to injury the driver that cancelled then took the trip when we requested one again, for which the charge was R111. Really poor, we trust you with our card details, but I’m really considering switching to cash or an alternative operator.
