Renault South Africa pathetic after sales service (2020 RS 280 EDC LUX)

My 2020 Renault Megane 4, RS280 LUX EDC picked up a "Check Stop start" "Check cruise control" error in January 2021. The car has been in and out of Renault's garage ever since. There are times when the car is at Renault for a few days where the technicians work with France to figure out the problem, and in this time I do not have transport. I'm becoming frustrated with the back and forth, and not the technicians are at a dead end. They are waiting for Renault SA to provide them with a way forward. Get a technician from HO to have a look at the vehicle, or someone from France. I have begged Renault SA to assist me in resolving this issue however there is a don't care attitude from the head office "as the car is drive-able". They are waiting for the car to breakdown on the roadside for them to step in and assist me in s****ping this defective vehicle and replacing/refunding it, since they can't fix it.

You pay an arm and a leg for a vehicle but you receive **** service from the guys up there at head office. You people need to catch a wake up, you can't drop the ball like this, when there are other brands entering the market waiting to eat you up!
