False rewards programme

Phoned Silverstar Hotel in Krugersdorp to check availability and make a reservation for 24-26 September. They confirmed they had rooms available but I had to book through Discovery. Logged in via Discovery web page and was redirected to Kulula. On the Kulula web site I requested Silverstar Hotel but was informed that there were no rooms available. Phoned Kulula and explained that I had just spoken to Silverstar and confirmed availability. Consultant explained that they only have four rooms available that are eligible for booking via Vitality and when those rooms are booked you can not get the 35% discounted rate. How is that fair? Can I please have a copy of the fine print for all the things you don't honour (In layman's terms please as I am not one of your many fancy lawyers). I feel you should be clearer on your terms and conditions. My last complaint was also ignored even though I rep**** negatively to an enquiry by Mr Barry Sundelson in which he enquired if my issue had been resolved. I emailed him at least six times after that but in vain as he never responded. You guys are abusing the system, and its sad that I can't do anything about it!
