Vehicles lights not working after installation of cartrack unit

After installation of the tracking unit from cartracker, my vehicles brights lights were not working, only dim lights were working and I told the technician to come fix and he was not able to fix the problem I reported it to cartrack on Friday 3rd September 2022 and a guy by the name Angelo from cartrack came to my place on Tuesday on the 6th/09/2022 instead of fixing the problem he made the problems worse now both bright n dim lights were not longer working wen he left from that day and he said cartrack will replace the switch they messed up and still my cars lights are not working. It's been 13 days later I still have no lights on my car. Today I called cartrack requesting that they need to fix the car but instead I was called by the same supervisor Angelo saying that he needs to come to my place n open my car again n take pictures on the wiring, his not even saying that he is coming to fix. My car is still new I had the car for only 2weeks already cartrack has messed it up. I drive with Hazards are night when I knock off if the sun sets whilst I am still at work. Angelo from cartrack is telling me that it will take 2weeks to fix my car. I was almost given a fine by traffic officers for driving without lights at night, I was also almost involved in an accident because the car following me couldn't see me, cartrack is not even offering me a courtesy car for time being. Cartrack has put my life at risk and also my job is on the line because of tracker. They need to fix my car.
