Unfairly treatment

On the 30/11/2017 Cartrack technicians came to replace their unit on my siyaya taxi, and I gave them a space to do whatever they had to do. They took very long. When I go to check up on then there was an accident. When Israel was testing their device by starting the car he didn't check that the car was on the gear. My siyaya bumped into their company car then to the wall. The front, back and the side is in the mess. Their boss Gerard Barnard came and he took the pictures. Gerard asked for the quotations I gave them to him, he send someone to come and access the car. My car today is till not fixed, i even went to their offices to try to resolve it. He is taking me up and down to push time for them to close, he promised to call me today but he didn't...ooh he won't call if I don't call, he doesn't care, he is sitting on a fat bonus and I am suffering because of their carelessness. I explained to him that that car put bread on my table and also pay for my rent including their premium...etc. It used to bring R700 daily before the accident and now it's bringing 200. This issue must be resolved before they close for Xmas. I also need my life back
