Review Poor service from the driver

I board on a 0600 bus from Lawley to Johannesburg with my 11year old son who goes to school at Robertsham. I was told the child pays half the price but the driver shouted at me all the way, even wanted to drop me off before my destination. He doesn’t know how to address customers, l only have a problem in the morning but other drivers don’t give me problems. His surname is Mngomezulu
