Union staff fight for salaries and wages, yet the very union dont pay salaries to their staff

This union employed me in June 2021, paid me half my salary monthly and even paid me short one month. Workers need to beg for the money sending the two so called leaders emails, and numerous whatsapp messages to pay workers, is disgusting to be enslaved, one would think your still in the apartheid era. We fighting for workers rights and one of them is to be paid and yet the very organization deducting members subscription fees can't pay there own workers. Its an insult to the labour relations industry and South African workers. To not get paid and care for ones family and this union not caring is almost like a crime on humanity. What is been done with the money collected on a monthly basis from workers and why can we not get paid.
