Renault worst service ever

I bought a Renault Triber from Renault Centurion. 700km's down the line the brakes started screaming and scratching noises. The vehicle was taken in 11 times to fix the problem after the last time it was taken in Renault SA said that the problem with my brakes will go away. Still struggeling with the brakes after they said its not a manufacturing problem. They will not fix the brakes because its not a manufacturing problem. According to them the roads i drive daily is the problem. ( Is the car then not made for SA roads?)

Worst service from Renault. Will not advise anybody to buy a Renault.
