Junk 'new' s**** car from FORD NMI PIETERMARITZBURG

I bought a new Ford ranger from NMI Ford Pietermaritzburg on the 30 September 2023. Returned the car within 20 minutes because it had CHARGER SYSTEM ALARM , POWETRAIN MALFUNCTION/REDUCED POWER ALARM, LOCKING DIFFERENTIAL ERROR. These warnings were there on the car from the 27th of September 2023. Ford was aware but they still gave me the vehicle. The centre console lid was also not closing because the latching mechanism was broken. They reset the car on the day but later the alarms returned.Car was taken back to Ford on the 9th of October , Ford reported that the alternator needs replacing , later after stripping the car for further investigation they said it's a wiring harness. Subsequently they said its an earth wire that was loose .I requested that they give me a new vehicle because of the multiple faults on the car they refused stating they reserve a right to repair the vehicle under warranty. When I went to pick up the car on 15 October 2023 ,it had a dent on the driver side door and the rear right side tyre had a cut. Car was taken by Ford to a panel beaters without explanation. They kept the vehicle until the 27th of October 2023 to do the repairs. I noticed that the tyre was replaced with a second hand tyre not a new. After picking up the vehicle from Ford I heard a noise in the engine behind glove box , wasn't sure where it was coming from. Took the car back to Ford on the 30th of October 2023 and foreman confirmed that something is wrong with the vehicle. He opened the hood and found a loose wire in the engine next to the battery. They said they will strip the car again and investigate what's the issue with the engine. The vehicle is only a month old and has spent 3 of those weeks at Ford for repairs. Clearly this vehicle is faulty from the factory and the dealer is unable to diagnose and effect proper repairs. I want Ford to take this car back and give me a new car as it is not reliable. I cannot drive a car that has multiple faults and noises in the engine while it is considered brand new. It is unfair for Ford to inconvenience me while I have paid so much for this car. I've received the worst service from this dealer and the level of incompetence is beyond anything I've seen before. Please advise on who I can escalate this issue to at Ford because the head office at Ford is refusing to take this issue seriously...
