Tempest Car Hire! A joke!

So I tried to get the Edgarsd Club promotion (book for 3 days and get one-day free or more) online but it doesn't work. Contacted them via Facebook, their branch in Cape Town and call centre no joy! I was contacted by one of their call centres and I distinctly said that I want to take advantage of the Edgars Club promotion, the fool gives me a quote with their normal rates and casually inform me that the Edgars promotion does not work. Why is it emblazoned on your website if it does not work Tempest? Bunch of idiots. I rather go to Europcar, much nicer, competent and great service with free upgrades even when you don't expect it.
