ICB Admin and Accounts department are a shem

I mistakenly selected an incorrect subject to book my exams, R650 per subject, when I realised this a few day lter, I sent an email, requesting that they realocate the funds into the correct subject and its been a back and forth via email, they claim they are not bale to reallocate the funds or even refund me, I have to pay that amount again to book for the correct exam and forfeit what I have paid already, we pay an annual fee, that should cover admin cost, yet we are being fooled like this and our monies are taken just like that, they claim they cant reallocate funds, a whole bookkeeping institute has no funds reallocation process. I am so sickened by how SA's are treated and how we just loose money even when trying to get education, its sick, they cant be contacted telephonically, we can only send emails, what sort of institution is this, what accounting rules are these, I feel like ive just been ****** at gun point
