Reward Program Nonexistent!!

I am very disappointed that your rewards program has been practically non existent the past few months. I have spent a fortune over the past 3 months and I have received nothing in return. When I place my orders online a note at the bottom of the screen states that the rewards system is offline and it will be updated at a later stage, but the problem is that the rewards are never loaded on my profile. I spent over R7000 in August, over R5000 in July and this month I have already spent R1500. How can I not be getting anything back for all these purchases? This is really unacceptable and I am very upset about this.
