Instalment recalculation breakdown

May I please get a calculation breakdown of how my recalculation of the instalment was done.<br> <br> My first instalment was meant to be R2049.07. I don't understand how my first instalment moved from R2049.07 , R1231.40 before I asked for a recalculation of my instalment, <br> <br> On the 20th January 2015, I made a payment of R45k into my account, *** and asked for a recalculation of my instalment amount. Then my instalment moved from R1231.40 to R1174.40.<br> <br> I don't understand how I made a saving of R57 when I made a payment of R45 000, into my account so I can pay less.<br> <br> I have been in a conversation with MFC since January regarding my recalculation breakdown. I feel that this is a ****, and I am not a happy customer right now. <br> <br> I want my money back so I can use it more meaningfully as paying it MFC is not yielding the desired results for myself.<br> <br> If I had received a sensible recalculation breakdown, I would have perhaps understood why my payment made a substantial instalment decrease of R57. <br> <br> <br> <br> <br> <br>
