renault website - book a test drive - is a joke

hi, I am looking to buy a new Renault. the internet is a great way to reseach anything. I logged onto the Renault website with difficulty , as it seems to be down more than it is operative. eventually managed to get on and BOOKED ONLINE for a test drive with one of the dealers. still waiting for a response?? did this 3 times , booking test drives with 3 other dealers , thinking that perhaps the dealer I chose in Bryanston was so busy that they did not need my business. but still no response from any other the REnault Dealers. what is the use of having a website , with book a test drive facility , that does not work, perhaps I should not be looking to buy a REnault. I am going to try the same BOOK A TEST DRIVE for other car dealers / other brands , hopefully with a better response
