Med24 outrageous admin fee

Good day, we went to Med24 Montana on the 14th of February with our child which we had an emergency. I would like to know why do you have to pay medical aid (not to go to government hospitals), and then also have to pay an 'admin fee' of R 460.00 at the emergency unit??? you end up paying so much medical bills and admin fees all over that at month end you don't have money to pay your medical aid. And it was in the middle of the month, that the reason you pay medical aid so that you can go to a doctor or emergency unit any time without paying when you don't have the money.
