Refund request

I have a credit facility with Capitec. Last month the October debit order went off. After payment was made, I made 1 additional payments towards the installment for November and another towards the balance , yet you debited the entire installment for November. I called your contact centre to which I was told that I made no repayment towards the installment, but rather to the balance - which is a lie.

I want my installment amount refunded as I already paid it or provide me with proof showing that I made 2 payments towards the Balance as your statements displays ‘repayment’ regardless of what type of repayment was made.
