Disgusting Support

I travel with uber on a daily basis, and unfortunately had to pay cash for a trip, driver didnt have change so I asked him to add it to the wallet, the trip was R57, and I paid with a R200 note, driver added R50 to the wallet and kept the balance. Contacted uber support and tried contacting the driver and all I am getting is stone-walled. Loss of R93 might not seem a lot but it is the principle of the matter
