Delta buses are worse than a nightmare

If you are diagnosed with high blood, sugar diabetes, or asthma, kindly stay away from using this busses simply because they will worse your situation. For example, they picked us at Bosman at 17H00, drop us in Johannesburg to catch 19H00 (to Cape Town). But guess what? At 19H40, we were still outside, waiting for the bus. No communication. Nothing.
