Appaling Service from the TGF group

I have a TGF card, I sent my wife with my ID & card to buy one clothing item for me and they refused to help her. I usually send her to buy with my card to TGF stores because I do not have time to use it. The staff & store manager by the name of Vinolia Mabokwane were rude to her, I called the store and they told me about a 'Dual card' that I need to have but I have never been told about such a card. As my preferred group store, I expect you guys to update me on such info ie 'Dual card' whenever there are such changes. I spoke to the store manager & I pleaded with her but she could not help. I am going to pay off my account and close it with the TGF group!
