Rejected by UJ with excellent Matric Results

I have a 17 years old son who has recently matriculated in 2024, he got 2 distinctions, 5 level 6s and only one level 5. I app**** on his behalf at University Of Johannesburg for Admission in 2026, to study towards a BComm In Accounting. My son got distinction in Accounting and Mathematics Literacy.

To my surprise I received a letter of rejection from University Of Johannesburg, their reason is he does not meet entry requirements for UJ. I think my son has worked so hard to attain such very good results in Matric and I am so confused, what is the entry requirement for one to be accepted in UJ. I feel my son is so unfairly treated, or perhaps there is something very odd going on in Institutions Of High Learning. I am so deeply hurt, confused I haven't even told my son that he has been rejected. Please Help
