Worst owners

We worked for this company, they moved us all the way from East London to Swellendam branch. We have been working for them since last year. My husband broke his ribs so I had to stand in and help on his side to the point where I got burnt out. We work 7 days a week very long hours, if you take a day off to rest you do not get paid, you are also only allowed to take of if they feel so. We worked 8 months for Wildx during this time we were told we are not employed by this company but are independent contractors, but yet they want to make the hours and days we have to work and the salary. On the 25th of May I asked if I resigned how long would they need notice as to today they never spoke about it or accepted it but on the 18th of June they wanted to come and tell us we are done working for them and have to be off their farm the 20th of June, I myself asked to resign not my husband but yet they also fired him so no reason. The past 4-5 months they have been using my personal bakkie for Wildx use I still had 40% + run on my 2 back tyres. They used my tyres to the point where they were smooth up and down between farms, all the service kits ect was on me my personal account. When I said I can't drive my tyres are smooth they insisted on getting tyres for the bakkie as they have been using the bakkie for Wildx. But came the 20th of June they went and deducted the money for the tyres if though they used my tyres but did not compensate me for the use of my bakkie, my tyres, the services or the wear and tear on my bakkie. They left us with less then 2 days to pack up, find a house and move all our stuff, we did not have enough money for our rent, deposit or any other bills due to their deductions even though it should be for their account since they used my bakkie. After talking to the owner on the 20th of June he told me that it is not his problem how I get of his farm, how we move or that our salary is short even knowing we have a small child who would suffer due to his selfishness, we had to go around and ask other people to help move our stuff.
