Worst dealership

Worst dealership in history. I was sold a 2013 BMW 320i m sport for R 233 000 which had 125 000 kms reflecting on the dash board. I realised when I took it to bmw after a year to get a quote for a service that the kms on the car were reversed. When bmw scanned the car keys they found that the actual mileage of the car is 226 000kms. The car brake pads and disc's, tyres were worn out when I bought it, which cost me even more. I tried to reach them but they have closed down in benoni I have no where else to go. It was such a terrible experience, now I'm stuck with a car financing debt with a car that's worth half the value of the loan ****it Maan!!!!!
