Rosina Sedibane Modiba school of specialization refusing to give me enrollment forms after giving us the acceptance letter.

Good evening Hello Peter On the 1 of September I received an email from Rosina Sedibane Modiba School of Specialisation , it was the acceptance letter confirming that they have accepted my son Keletso Mokoka and even send me a link to apply online I did so. Today I when to collect the the forms because they told me to come after I have received my child report to collect the forms only for them to tell me that they have declined the acceptance because my son failed mathematics, at first they didn't say anything about the results or anything. So I will like Hello Peter to help me regarding this matter please I also have the acceptance letter with me
