Old buses & not suppose to be on the road

On the 6/11/15, As I was travelling from Pretoria to Umtata via PMB, the bus was late by 2 hrs & they never communicated that to the passengers. They organized the bus to take us to J'burg where we got transferred to bus NO 155. The bus had a breakdown in Mount Frere. We had to take CityToCiry bus which was the 3rd bus.On my way coming back to Pretoria with bus NO 158 the bus had a problem with fan belt @ 19:30 & we had to wait 4 hrs between Qumbu & Mount Frere in EC. They **** to us saying the bus is coming from umtata though it was from EL. As we got transferred to the 2nd bus NO 111 @ 00:10am we noticed that it doesn't have power in the hill it was struggling to go forward. As it was going up the dangerous curves of Maritzburg around 4am the bus stopped on the steep road and refused to move forward instead going backwards with passengers & trailer. We jump out of the bus because we were scarred of going down with the bus. We had to walk about 2-3km to get to the bus that was waiting at the end of the hills. In PMB we had to boycott to get another bus NO 156 which was very slow on the road. I left EC @ 17:45 Sunday arrived in PTA @ 14:35 on Monday I couldn't go to work.
