Exploiting youth owned companies VHP Holdings

I am a 32 yr old female who had worked for this company in 2018, as they said that they are big on assisting youth blah blah blah... I have worked for ridiculous money but I didn't mind as I wanted my company to grow and empower myself. I have tried on various occasions to get my money from this company which is called retention. A percentage they keep behind after people have moved into their houses and have lived in there for 3 months or more. That was 2 years ago. I have sent multiple emails, have called... these people just ignore me. I am trying to empower myself, I even went back to college but these people are discouraging me from even going back into the construction business because of how unprofessional they are. They even deducted uif back then, which I found weird as I am a contractor. I just want my money with no drama. It is owed to. My own money
