Renault kiger AMT worst car

We bought a new Renault Kiger AMT on a Tuesday and I drove to Gauteng on Thursday morning, the car was shaking and making funny sounds, steering wheel also making sounds on Saturday I took the car to the nearest branch which is Renault Midrand and I told them that I don't feel safe to drive the car back to Polokwane while it is faulty. The dealership in polokwane refuses to cancel the contract even though we not happy with their cars. Renault is a very bad brand and will never recommend it to anyone. CPA says that the dealer needs to insure that they sell right products which means good value for money.
