Please I'll like this to get to the relevant authorities. I really don't know who to report this issue to

My brother gained admission into this very university and after paying an acceptance fee of #30,000 , school fees of #89,000 was paid which includes everything as shown in the break down list from the schools portal. The school had to be requesting for another fee for medical fees, administration fee which was already included in the overall fee of #89,000. I mean, THIS IS FRAUD! DAY LIGHT ROBBERY!

Please i don't know how this can get to the relevant authorities.. I just thought of bringing up the issue here.
