Absa Vehicle Management Solutions

I financed my car with Absa Vehicle Solution, on the 21st of April I paid lump sum of 40.000 rands towards the settlement of my car, the settlement was R42.000. When I paid 40k there was two installments which was not allocated to my capital I pay 4200 every month for my installment. I wrote to Absa dealing with the consultant Christine Sinclair ask her to stop the billing in my account since I have paid a settlement and also give the refund cause now I paid over and above, she responded said her laptop crushed she does not have all my information we spoke over the phone agreed to make all the calculation and refund me also stop the billing with my surprised billing continued this month on the 25 of May R4200 was deducted in my account. I wrote another 3 emails and phoned her but she told me absa had changed there IT company that's why things are slow then she sent an email to her manager Achary, Verushka to check if the payment has been allocated, still, there was no response. I wrote another email on Thursday the 27th of May to ask if is the way Absa treats their client or it's only happening to black customers again no response. I can't keep on paying for something that I have settled which means now there owed me 3 installments that I paid over and above my settlement also the sad part I can't even reverse this billing cause there take directly from my salary. I am so disappointed in Absa such a big bank that has *********** staff.
