Greyhound bad service

In December I was travelling from Park Station to Cape Town. The bus was supposed to leave at 18h30 but instead it left at 20h00 we stood there with no one explaining that there is going to be a delay. When we finally got into the but the aircon was not working at it was hot. I travelled again 24 Feb from JHB park station to Cape Town and the same thing happened the bus was almost three hours late and we had to ask no one came to tell us what was happening. very disappointed at Greyhound's service.
