How to proceed with my labor case if I don't have money to pay the court fees?

I am working with one company and the company terminated me. I made a labor complaint and received the labor complaint number.

I brought all the documents they requested and went to Injaz - Al Ain as my visa is Al Ain. When I visited there, Injaz people informed me to pay AED 30000 to transfer my case to labor court.

Please advise me, what will I do?

Last 3 months I don't have any salary. I need to get more than 300k as l worked in the UAE for more than 15 yrs. This is a huge amount that an employee can pay as there is no salary given by the company.
