unfair dismissal & treatment, ********* workplace

I've been employed at this company for about 6 months now and I've always been threatened, I never get paid on time, I've always been working over time but i never get paid for it & customers are always complaining about the terrible services. Customers complain about stock (there is never any stock) the money market is still not in working order. I was threatened countless times where the managers would threaten to dismiss me if I did not do things their way. I'm currently unemployed and I am still waiting for february's salary, when I call them they do not respond to my calls they send me messages stating that there is no money for me not taking my finacial situation in to consideration at all, they treat each and every emoloyee the same way that I have been treated. I was unfairly dismissed because I had no transport one sunday morning I was threatened by my manager and then told not to come back to work the monday. I am now chasing after them for my money but they instead send me text messages stating that I shud ask my husband for money. I'm stuck in a financial difficulty please help what should I do?
