Webuycars - manager took car to go on holiday with although it was as good as sold.

I enquired about a car on their website, one located at Silver Lakes in Pretoria and the stock number is 43A6C7334, a 2015 Renault Sandero 900T. I was contacted and I app**** for finance and was approved. Yesterday ***2 I went to the Silver Lakes branch to test drive the car but was told it is gone and sold. Yet the car is still for sale on the website. Nobody even knew where the car was since it and the keys was gone. After much confusion I went home. This morning I was informed the car is not sold but was taken by a manager to go on holiday with it. So what is being done with the car that I wanted to buy in good faith? Being spun from every robot? Driven of curbs? Maybe a child throwing up in it? How many kilometers is being added from the advertised 56,000km? 100? 10,000? One will never know. Naturally everybody is very sorry and I shouldn't worry etc but how is this in any way acceptable? The sales person tried to contact this manager person who took the car but as I'm typing here this person couldn't be found. Really this is a worse horror story than anything you'll ever see in a movie. I really urge people to not do business Webucars because what you see on the website and what you'll get - it won't be the same thing.
