Poor condition of public bus

This morning I took the bus 852 to school. When the bus arrived at the bus stop, I noticed that the front doors were open even though the bus had not stopped yet. I thought at first that maybe the driver may have opened the doors a little early but as the bus started to move again, the front doors did not shut and the driver later explained that the doors were spoilt and could not close. This is actually quite dangerous as people may actually fall out if the bus stops or turns abruptly.
Unfortunately, the doors were not the only problem. A few stops later, a lady wanted to get down and pressed the "bus stopping" button. However, the light did not flash up. She tried a few more times but it still did not light up and the other buttons also did not work. The alarm system was not functioning. She and a few other people then called out to the bus driver to stop at the next stop. However when the bus arrived, the back doors did not open. The bus driver then said that the back doors could not open and that we had to alight from the front.
It also became extremely humid after a while in the bus, which I presume is due to the air-conditioning system breaking down.
When the bus had almost reached my stop, the bus was suddenly filled with a loud wailing sound. What had happened was that the card reader has stop working and it was the source of the sound.
I feel that the company which owns the bus should conduct regular maintenance checks on the bus to ensure that the bus is in good condition.
