Vitality is Deceiving

I am really frustrated. I used to do all my shopping at Dischem, so that I could get the Vitality cashback, but now I see hardly anything there is Vitality Approved... on YOUR pdf it says diapers, but I have noticed that you no longer get money back for Huggies Extra Care or Pampers Diapers. In fact I couldn't find a single diaper that is Vitality approved.. EVERY month this year less and less is linked to Vitality at Dischem and your people cant tell me why or where I can buy nappies etc that are vitality approved. Its like you no longer provide a cashback incentive. I used to be able to get the Maximum cashback and this year, even though I still buy exactly the same stuff I am hardly making R300.. I am close to just cancelling.. Don't join VItality.
