A Lazy Technician and mismanagement

I have asked them to fit my vehicle with the device and they did but the technician who was fitting it did not connect the engine cut off switch which disables the engine if the vehicle is ****** and when he was called and asked why he never connected the wire he said he was lazy to do it but I heard he was retrenched that is bad but good for customers like me whose vehicles can be ****** and would fail to disable the engine. One would wonder how many vehicles has he installed but was lazy to do it properly. I am still waiting for another technician to reinstall it properly.
