Not keeping their promise

Ireceived an invetation to go for training and it is paid training days. I went for training at Europrime Lakefield near Benoni from 2 to 4 August as reservationist and then at Europrime Airports for 1 day. At the end of day 4 I was told via watsapp that I did not make it. I asked about the payment for the training days, and manager Angelique said I will be paid. I waited and a few days later nothing yet. I send emails, now I am blocked. Asif is one of the bosses, and he said payment on 25th. However BCEA says they must pay me within 7 days. They just block you if you srnd messages, and do not call back. All I need is my money. Please !!!!
