Renault customer care failure

My car a Renault Clio was involved in an accident in March 2021. As of July 2021 Renault has still not been able to supply the necessary part. They have ordered the incorrect part twice. Now I have been informed that they are still in the manufacturing process for the replacement. At no time has the company contacted me to keep me updated. I have spent over R15000 to hire a car as I am without a vehicle. They will only supply a hired car for 7 days although it's been 5 months that I do not have my vehicle. The company has failed me on many levels from unreturned phone calls, changing the story on when I will get my car back and a unfriendly and unhelpful staff. I would not recommend this company as the after sales service is atrocious and parts are apparently very difficult to come by.
