No pay for work done

I was part of the hairdressing team for the Durban Fashion Fair at the ICC Durban in Aug 2017. Its has been almost six months now and I still havent received payment!!! I had to travel from Ballito to Durban everuday on my own expense plus work untill 11pm. I have contacted many people and no one seems to want to help.... I think its is very unprofessional and un acceptable!!!!
