Webuycars.co.za suzuki alto 2012 model

I have been looking at a Suzuki alto to buy from webuycars. Co. Za. I phone the the no. Which I found on there website and spoke to a sales person that told me the car is available and he will ask someone to phone me back which never happened I phoned the next day again and one of the other sale people told me the some thing that it is available he will ask someone again to phone me which also never happened, Today I phoned and they said it's still available then I ask if it's possible to come and buy the car on Saturday and the lady told me yes she will send me there banking detail then I can pay R5000 deposito which i agreed on but just after she sended me the banking details she told me that the car is waiting for finance she can't sell it. The lady I spoke to is katlego Sonia. This is unacceptable I will never do business again with webuycars silver lake
