120 point inspection not done properly

Had 120 point inspection, they said that the aircon and the window mechanism was working . I'm thinking that the aircon, just needed re gassing. Took it for that, just to find out its in bits and will cost me about R5000 to repair, new condenser, pipes, regass and labour. The next thing is, the window mechanism needs replacing. the person who inspected it just banged it a few times and it stared to work. But not for long. They are, so called members of the RMI. hope that changes. I purchased this vehicle, on their report.
