Claiming unpaid salaries upon termination of a limited labour contract

I work for a company that pays only on a commission basis. I signed a Labour contract for two years with them, where I didn't receive any salary.

I also signed an internal contract that states they hire me as an Agent and on a commission basis only. Now, they have terminated my employment after two years.

I would like to know, am I entitled to claim my salary before I sign the cancellation documents, provided I remained unpaid up to date.

Thank you and look forward to receiving your reply at your earliest convenience.
