Rudeness - Consumer Complaint for Translux - Head Office

We are traveling from Jhb to EL,the bus is freaking freezing and I asked the driver to switch off the air con and he replied very rude telling me that I am disturbing him.How is that? For what I know the customer is always right and I have a 2yr old child who will catch a flu and I'm the only one who pays for his medical bills.I don't understand how selfish some people can be.
