****med by Renault Boksburg

I'm super frustrated. I bought a brand new Renault from Boksburg, and the car has been giving me problems since day one. The salesman said it was a brand new car, no issues, but now it's making loud noises when changing gears and reversing. Took it to Renault Benoni, they reset the clutch settings, said it'd be fine. Didn't fix it. Same thing happened again. Spoke to the technician at Renault Boksburg, and he admitted these gearboxes have problems! 😤 Car's not even 6 months old. Feeling ****med. What can I do?
