Refusal to supply Tablet

I refer to complaint reference ***. I was called by Mr John de Kok about the no stock issue. Mr de Koks response was that Game do in fact have the Tablet I was requesting. Apparently the stock they have is kept for Contract customers only. I asked John why this was the case and he couldn't give me an answer. How can Game keep stock aside for Contract customers and not for Prepaid? Why is Game differentiating between customers? Am I not a valuable customer because I'm paying cash for the product? I have supported Game for over 10 years because of their superior, excellent service. But if this is how they treat their customers I need to take my business elsewhere.
