R400 Promo false advertising!

So yesterday I phoned Outsurance for a quote on my car and houshold insurance. After I gave them all my details, they were unable to beat my current insurance by a long shot. They were 30% more expensive and 3 X the access on a like for like basis. At the end I asked about the R400 promotion and I was assured that they will send me a email with all the details. After some time I got a sms with a unique pin. This unique pin has to be entered into their site Once they email you a link that only you can see. However no one sent me a email. Although I did get another promotional email from them shortly after my phone call but nothing about the R400 promo. Searching on the web I can see this is a normal tactic of them not to pay the R400 as a lot of people will just give up. This is false advertising from Outsurance side. My thing is that if they can't even be faithful about a R400 promotion, how on earth can you trust them as your insurance company?
