I need my child to register with them, however they are not transparent as their fees are not on displayed online. And my child called them and the lady who assisted her to my child to pay R600. R300 is for application and the other R300 is for registration and its state on their email that the other R300 is refundable if my child has matric certificate. However due to their expensive fees, I could not afford them and decided to register my child elsewhere. Now I need my R300 they are taking me from Pilar to post since March 2022.
