Worst bus ride ever

Probably the worst travel experience of my life. Surprisingly the bus wasn't late, but oh my word the toilet. The door didn't close and the smell was horrific. I was on that bus for 30 hours from Cape Town to Durban, and nothing was done about the smell. A security guard even came to the back during the trip because apparently someone had called and complained. All he did was check that it flushed and immediately went away again. I felt trapped as I couldn't open any windows, and when I wanted to quickly go to the bathroom at a stop the driver rudely shouted at me, saying no we're leaving now and I can just use the one in the bus. Also very dirty and unhygienic. Would 100% not recommend.
