Extremely bad service

In 2023 traded my Ford Kuga in for A Venue, test drove the venue, when collection of Venue was done they gave me a different venue full of scratches and did not drive the same as the one I test drove. They next day took it back but they said they can't cancel the deal as they already settled my Kuga, they said I could only choose a different car. With no other choice then to choose a creta 2022 which I was not happy with. Sales person Andrea said that after a year if I want to I can trade the creta in and won't loose on the car. About two weeks later my debit order went off for the Kuga, meaning that the kuga was not settled as they said. When stating this they had nothing to say. I've been to Hyundai Wilropark again Now in April wanting to trade the Creta in die Tucson at R400 000, but been told they can't settle the creta as I owe to much on it and I took a loss on it.. I would like to know what sales personnel and Managers are employed at Hyundai that Cant tell the truth to clients, when buying a car and trading in. Now I'm driving a car that I can't trade in at the same place it was bought. Hyundai was a great drive but why should we support a franchise that does not perform. I called Hyundai head office at the same time and left message to be contacted back. After almost 2 years not reply. Very bad service
