Bad panel beater boss

This person is a problem to some of us here in South hills. The Boss owner and only worker now has been giving us a bad name off *****ing and we have a state witness saying that his own son also told him to stop miss placing his stuff. He under pays us and sometimes we had to tell him we calling the cops in front of him then he wanted to pay. Don't know if he is allowed to do work from his house. He also takes company cars. He has been doing this with more than 3 people and we want to stop it. It was also done to me today he also likes bringing you down a lot emotionally. Here is his contact info +*** Dawie
