Unhappy customer

I ordered a Krusher burger meal from KFC Parow total came too R71,15. Was delivered by a very *********** driver called Celestin. He had no change when I offered him R102 so had to rush to the nearest café to get change. Cane back with 2xR50. So I payed him R52 and went back inside to get another R20. Total R72 order payed. It is totally not my fault that the driver did not have change. All drivers should have a float on them or change. I am a very unhappy customer. This driver should be release from delivering any more food to anybody. Now the app says I am R71,15 in arrears. How so did Celestin take the R72 I gave him for himself??! Makes you think how trustworthy is the drivers working for Uber Eats?
