Employed people but not paying them

They post on Facebook that they are looking for people to work for them that you get a basic salary plus your commission so I went for an interview but I had this funny feeling about this place because it was really unprofessional after a few days of training for which they don't even pay you, I dug more and became very skeptical about this place, but I needed the money because I have a child to feed, so after a few days I resigned the guy who hired me, he said he will pay me for the days I work it was in October I'm still waiting for payment and he doesn't even read my whatsapp messages so just be careful of them
