Dispute on account balances

I have taken a loan with RCS in 2012 for an amount of R25 only.My account debits has been debited successfully each month as arranged up until the I fell ill and was unable to meet the monthly required repayments amount.RCS consultant from the billing department called me and advised that my account is in arrears,to which im aware then my situation and make payment arrangements for an amount of R830 per month then I also asked if interest will be added onto the arrears amount to which stated No as there is already a monthly interest charge when the loan was initiated.<br> <br> I received an sms notification during the month of May 2015 regarding the current balance I owe but to my surprise the amount is far more then what it is supposed to be as per the last consultant I spoke to.A call was then made to RCS the 24th June 2015 I spoke to Christelle which she transferred me to Lethando in the Billing department and according to her a restructure was issued on the account in November 2014.My view on the balance given is incorrect as the account is owing the initial loan agreement fee instead being decreased after payments is being recived via debit order from my bank account each month.
