Broken network cabinet

I hate irresponsible people. I now that it is not possible to avoid such people completely as everywhere you can find people who have problems with that. Whenever they are supposed to do something they have problems with that and they can be perceived as irresponsible people. I can^t understand why they are acting like that. They don^t feel that they are doing something that is connected with other people as well and if they make a mistake we will all have to pay for it. Like I have a friend that picks me up when we go to school and he is almost always late. That is frustrating because our teachers don^t like it as you can imagine. Let me give you another example. I have ordered network cabinet recently and I really couldn^t wait for it. When I finally received the package on Friday I was really disappointed. It is not due to the fact that it was so late but because this network cabinet was broken. I couldn^t believe in it. How can a company act like that and send someone a broken network cabinet. I mean it is natural for me that they should check what they are selling. There is also a chance that this cabinet has been damaged during the transport but I don^t think this is the case. What do you think about it? What should I do?
