DCJ Aircon bad workmanship caused damage

Stephen du Preez replaced my vehicle's aircon compressor on 7 December 2015.<br> <br> Bad workmanship caused the new compressor along with other parts of the aircon system to break shortly after.<br> <br> I have been trying to contact him by email and phone. He does not respond to the emails. He also adds customer's numbers to a block list on his phone. From other complaints I have read about the supplier it seems to be normal practice for him.
