Poor customer service from game store galleria Amanzimtoti

Good day,

Tried purchasing items on my game card from game galleria, after the items were scanned by the teller(before the items were scanned I have told the teller we are making payment on our game card) , I was told that I needed a copy of ID to make purchase(could have asked for proof of identification before items were scanned) , after telling the teller I do not have a copy of my ID and that I've made purchase from another game store previously which I was not asked for my ID, which in return the teller asked if I could speak to her manageress for assistance, upon of her manageress arrival, she just asked what was the problem, after explaining she says that her store never let customers use their card without a copy of their ID, she then asks for a copy of the till slip which I've purchased the items many months ago(who walks around carrying slips of their purchase done about 5 months back ?) , then when I ask to check on the card on where the items was purchased she says it cannot be done and walked away without offering any type of assistance.... Due to her rude attitude we made cash payment of the items in total in excess of 2k,and requested to cancel our game account as we do not wish to shop from a game store again due to the manageress rude behaviour and poor customer service s****s, if she doesn't speak to her customers with respect irrespective of their age, game will be losing many more customers.
