Good Day

I have a question, I was employed at a legal company from November last year.
I was never given a contract to sign, and I was not paid a salary or even provided with a salary advice.
I resigned at the end of January as I could not continue working without pay.

I would like to know how I can go about getting my money out of this guy, one other former employee has already gone to the labor department and the ccma but this guy has not paid.

Can I not proceed on the basis of constructive dismissal?
