RCS Call Center/ agent and Statments

I was kept on hold for a whole half and hour and still the call center agent could not assist me. I have opened the account about 3 months ago, and ever since, I have to phone in every month because my statement on my phone and the statement they send me differs. This is a RCS card, so I pay RCS interest, service fees and protection fees. I do understand that, but then I also pay Makro, interest, services fees and protection fees and the same for Game. So my installment is R500 from RCS and they deduct R141 for all the services another R141 gets deducted for Game and Makro services and that is the part I do not understand, According to my knowledge it is an RCS account why I am I paying protection fees, and all the other fees to the other stores and now i have no available credit. The agent said that it is right and that is the way it is but last month I paid my account and then the amount i paid on the account was available. This month it don't work that way. The month before I paid double my installment my statement said I am in arrears. I really don't understand and trying and waiting for a Supervisor to contact me since my first query 2 months ago still nobody got back to me.
