Chas Everett Polokwane abusing power

Hi I am Pheobe Mphahlele I started working at Chas Everett property in Polokwane last year, I worked for a period of 8 months without getting paid. When I started working there they made me pay R4500 for registration so I paid. It took me 3 months to start selling houses, using my own money for petrol then I noticed that all my houses took time to make payments so around April I started to look for jobs somewhere else. I agreed with the principal that I will work at a different job and still sell houses. All my houses started to register around June. When they paid me I asked why is it that the money that I got isn't the money that I was expecting, they took more than 80% on most houses I sold. When I asked why I received small money they said that's how they operate but when I contacted the Chas Everett head office they said that's not how they operate, they told me if I want to take it further I should get a lawyer of which at the moment I am currently staying in one of the property's that I was managing which I made payment for a period of 6 months without skipping any payment even when I was not getting any income so because I started to question the money I received and why they won't fix the problem of surage at my door and the water leakage of gysers of the premises of where I stay because I am currently a client no more a worker at the property suddenly out of the blue I start to receive letters of overdue and letters that say they will throw me out of the premises. When I started to stay in the premises they said I shouldn't pay deposit because I was working for them paying rent every month. I feel that they are taking advantage of me as a person and abusing me as a tenant. And now they are telling me I owe them on amounts that we never agreed on. Please help me ***
