REFUSING TO PAY ALL MONEYS OUT OWING

I work for the mine as the Swimmingpool caretaker for 5 years, and was on a fix term contract. The beginning of Jan 2015, my contract was not renewed, and I was told that my area of responsibility is going to be looked at and improved, Im going to have more responsibility. So, my contract was not renewed then. Every month I still get my salary from the mine. I went to the offices where I was told that I am no longer needed and refused to pay me my monthly salary. I know by law that a employee can not be chased away just like that. I still got my salary every month, I asked to be signed on as permanent and put in another position - as stipulated in my contract, but with no avail. I handed in time sheets every month, and did not get paid overtime and weekends and public holidays, it needs to be paid out to me, but Mr Nkisi refuses to pay me. He gave me 1 months notice and I will get 2 months salary with my leave pay. After tax there will hardly be enough money left . I think I am entitled to all my money I have worked for, then I will leave the mine. I also emailed Nick Holland, CEO, but no answer as yet. It is discrimination and unlawful practice!!
