Advertising car with *****ed mileage

Cars4you in Doornfotein Johannesburg under name Goldennn Autos advertised a 2022 Suzuki swift with 69999 km at R130 000.00. I got attracted by the make year and mileage and I bought it and collected it on the 15 August 2025 and upon collection it showed 70348. On the 19 August 2025 it was taken for inspection and it was discovered that the correct mileage was 100809. I contacted the car dealership and spoke with them but all they did was to dismiss my complain and not willing to resolve this issue and to replace the damaged wheel cap and said I am the one who damaged it which was incorrect it came like that and I reported it the same day after collection. This car dealership advertised incorrect which is against the law and they acknowledged but didn't want to resolve or correct it. All I want is value for my money.
