peach payments

i was applying for a online school ,i haven't even chosen the platform i want yet or confirmed the amount to be paid my child hasn't even been accepted yet .but i get a whats app from peach payments saying i must pay R4300 to there link which is way more than the most expensive course offered by the school ,so where did they come up with this amount like i said nothing has even been confirmed with this school . i feel these guys are trying there luck . i will be making a stop at there given address as it is not far from me .
