Bad customer service

I purchased a new Ford Ranger Wildtrak on 20 April 2018 On Saturday 21st i noticed a dent and a scratch on the tailgate of my vehicle.I took the car back to the dealer on Monday 23 April 2018.The salesman Henry took the vehicle to valuations for them to check.I told them i do not want a damaged vehicle that i paid R 510 000 for.They called the sales manager Rene Victor She had a look at the vehicle and said it has not been repaired before that is how they received it from Ford.She offered to change the tailgate with another vehicle they have in stock.The vehicle was brought up from storage and that vehicle also had a damaged tailgate.I said to Rene that i am not happy with the spray work on the vehicle and her answer was"THERE IS NOTHING YOU CAN DO ABOUT IT SHE FURTHER OFFERED NOT TO REPAIR THE SCRATCH BUT TO TOUCH IT UP.During a follow up call from the dealership I was told that i will receive a new tailgate for my vehicle once they receive another vehicle from the factory.That would mean that another customer will get a damaged tailgate on his vehicle.I would like to warn other customers of this strong arm tactics used by this dealership.REMEMBER THERE IS NOTHING YOU CAN DO AFTER YOU HAVE PAID
