The worst choice I've ever made in choosing buses

The worst choice I've ever made was choosing this bus, as i walked in on Monday and booked a ticket to ladysmith for Wednesday. Before booking i asked the guy if cancelling will be possible should my plans change,with his big head he agreed. As if i knew that i had to postpone the trip ,so with the advantage of cancelling the booking, i had to go back and ask them to cancel the booking. I was told I'm going to get only half of my fair and not today but after 15 working days...Ok i had to ask them to reschedule the trip, only to be told i have to add money again of which when i calculate its more or less a quarter of what i have paid already ....if only i was told what the procedure of cancelling or rescheduling will be ,then i wouldn't have booked at all..but thanks a lot for the worst, i can't stay for this kind of treatment as if i ride for free
