Greyhound — greyhound buses are not reliable enough

Don't take greyhound, rather go for cityliner or catch a taxi. I got onto bus 1701 GJND1002 Joburg-Newcastle-Durban at 10:00am this morning and only arrived at newcastle at 18:00 this evening because of what greyhound said in there smses to be a 'technical fault' and 'road works' when actually it was because the bus broke down twice and they had to send a mechanic from jhb. We waited in standerton for two and a half hours so that the joburg mechanic could tell us the same thing as the standerton mechanic. The hostess of the bus told us that this happens regularly. I want to know how often evaluation checks are done on those buses. The problem with our bus was that everytime it came to a complete stop it broke down. Pathetic to offer that kind of service after I paid R260 for my ticket, cityliner is only R150, however I chose greyhound because it is apparently the better choice. Well apparently not!!!
