African Bank Loan Settlement

I took out a loan with African Bank and last instalment was supposed to be August but i asked to settle full balance in July called the bank and asked to have the full outstanding amount cleared but come debit order date only normal installment comes off on 28 July. Come 29 July i call the bank again and i ask again for the balance to clear my loan, got the outstanding to settle and settled immediately while i had the consultant online and all was sorted or so i thought as everything had even been cleared from the banks app which i use.

28 August debit order comes off for the monthly installment i was normally paying i go on to check the bank app and it was now showing i have an outstanding amount of R135.11 and there is a bank statement also that appears breakdown shows R 2.16 of arrears interest the rest is service fees, vat & insurance costs. I call the bank countless times and all consultants can tell me is i owed R135.11 which i should have either underpaid but has to settle now including service fees and other addons. #WIN
