Greyhound poor services

Greyhound customer services is not exceptional. My bus was suppose to depart park station JHB yesterday at 20:30 but we only left park station at 22:00, we didn't even receive an apology about the delay. In less than 10km travelled the bus developed a problem, now we stuck in Midrand and we still have a long way to travel, travelling to Bulawayo Zimbabwe. The customer service is so poor for the amount we are being charged. The bus's default implies that the bus was not fully serviced, now we somewhere in the middle of Midrand waiting for another coach, I am truly disappointed on their poor services rendered to us, it gives me the idea that we are not valued as customers, how can people travelling a long distance be given a bus which has defaults. I am very frustrated as it is, as all my plans have been ruined by the delays. To the Greyhound company please ensure that your buses are fully serviced, this also adds to accidents within our roads, may our safety come first to you!!!!!!
