Jaguar Land Rover Pietermaritzburg is a Nightmare

my Engen light has been on from last year, August 2021 they have tried switching it off but in two days the light comes back, one of their workers had told me that usually if the car does that it means they have to change all the sensors and its expensive so they don't tell you they keep on switching off the light especially if you are Black they don't take you serious. i'm tired and im never ever buying any car from Jaguar Land Rover!!!!!! my car is now loosing power its maximum speed is 80
