They look to be a ****

I went to Labour Law, Rivonia. My ex Company paid them out in full on the 20th July and I have been asking for my money since then. It is now October. Nobody in the office knows where my file is, they have invalid excuses for everything. The laid back attitude there is as if they do not care if they pay you or not. It seems that they are getting paid out by multiple companies and keeping the money. I do not know what to do about this and am infuriated
