Still no feedback from Renault SA from last review

I purchased a Renault KWID from Renault Ballito in May 2019. They have the most awesome sales team, but their after sales service team leaves a lot to be questioned. I had an accident on the 03/08/2019 and my vehicle was towed away to the Renault inspection site. On the 14/08/2019 I received a quote from Durban South Panel Beaters with an expected turnaround time to have my vehicle repaired of 10 days. To this day I have not received my vehicle. I received 2 letters from CMH Nissan - 1st one advising that my parts would be delivered on the 18/09/2019 and then an updated letter on the 03/10/2019 advising it will only be delivered on the 18/10/2019. I have made 3 payments towards my vehicle to date for a vehicle I am not in possession off and I have excess of R15 000 to pay for when the vehicle is ready. How is this fair to me that I am paying towards a vehicle I don't have in my possession and have no indication of when I will be getting my car back.... Renault SA has inconvenienced me by not ensuring I receive my car back as agreed when the quote was provided to me. and for this they have not even secured me in a courtesy vehicle so I am left without transport. to provide me with a courtesy vehicle they insist on me making a payment of R1500. all this because they are not able to provide the required parts to the panel beaters to fix the vehicle... I strongly believe that I should be reimbursed for some of the costs I am having to cover for their incompetence and lack of service.
