Negligence administration lead to incorrect payment dates and amounts

After trading in my Stepway, I was approved for finance I went to collect on 23rd November my Renault triber 2022 in which on our discussion with administration lady Mphoza we signed for installment of R3 341. And I was to come back on 30th November so that my first installment can go off end January 2023. So I left dealership. Then 29th confirming to go back, I was texted that I no longer needed to come and explained on call was that already papers are submitted and my payment will be in December 2022. I disputed that and went to Renault Alberton met with the lady who still gave me attitude and not apology as it was mistake from their side competing incorrect salary date not according to my pay date. And she also told me that she asked on Saturday 26th that I be called to sign again but none of them with sales guy did that but left for home instead. The guy offered to pay that installment but now I have to wait in which I thought that would settled by month end not on his incentives. That has put me in financial state because I had taken care of my kids school stuff knowing this would be sorted.

I then on 28th December call MFC to confirm debit check which I had not received, I decided to confirm payment amount and to my surprise it was now R4700 no longer R3 333. The bank sent me mortisation showing incorrect principal debt. I called manager Thabiso he asked I come through. At my arrival speaking to the admin lady she confirms an overpayment by the bank to Renault and that affected my debt. Now it has since been 3 days and that issue no sorted and debit order I cannot afford is now due and can affect my credit record. All this by mistakes caused at administration side.

Thirdly I have since come to Renault 3 times indicating that car when I break it makes a screeching sound. First time the guy told me its the rain, second timeThe mechanic adjusted the handbrake which I cannot recall his name, now same day 28th December I report same issue instead I was asked by the manager if I'm harsh breaker with such a new car how can that even show up and mechanic is on leave. Which I'm remaining with problem.

I would like to say I need a tangible solution from Renault Alberton. Their performance has affected my life causing me pressure and stress. I am truly regretful displeased with their service.
