I'm so angry and fairly dismissed

On Friday 14th of July Bongekile told me that I must go at their office on Monday they want to see me so I went there I found an Indian lady and she told me at Makro Amanzimtoti they like me and I'm doing my job perfect and I don't have a ******** record but the problem my credit record is not good it either I resign or at Makro will found out and I won't get permanent and I will never work for Makro anymore. I ask her if I resign are u guys I'm going to save my notice or wait until my contract is finish. She said no I must resign yesterday and I said give me time to think about it than I will answer her today. When I get home I think about it and than called her I told her I'm not resigning it either they fire me or terminate my contract and which law states that if you are on debt you must resign? If they fire or terminate my contract I need it in black or white and they must pay me until our agreement. Today Candice called me and she said I must make arrangements with the store of how much I will pay every month and I will work on another company. Bongekile didn't want me to work at Makro from the first just because my manager likes me and I'm doing my job perfectly. This morning Bongekile brings someone new to work on my place and told them she doesn't know what happened to me mind you I haven't resigned or termite my contract. Bongekile she selfish and she knew that they like me. Im not going to let go just like that I will fight for what my right.
