WeBuyCars false Advertising

I contacted WEBUYCARS Silverlakes in regard to a 2010 White X5M. The mileage advertised on the website was 30 000kms with service history and they advised the vehicle was available. I then contacted BMW to confirm the last service, which they informed was in 2014 and the mileage was 42500kms. I then contact WeBuyCars to confirm the milage again, the consultant once again advised the vehicle was available and advised he will physically check the millage. He called back after an hour advising me the vehicle was sold. Makes you wonder whether the vehicle was sold or they realised that we picked up that the mileage was cahn
