Kia south Africa

I am in the market for a Kia Seltos 1 5d auto.when I go onto autotrader.cars.co.za.carfind and surf 4cars.i find the seltos for sale at Kia dealers across the country.when I call the dealership they all say the vehicles were sold and when I asked when was it sold i am told over a week ago but yet still shows for sale and they haven't removed it yet.How often is the adverts updated by the dealerships as it's pointless looking if the adverts dont get updated.
