Online bad experience-misleading information on sale item

The worst store to buy anything online.Their online information is very misleading .I first bought the item last month after 2 days I received a refund without any information regarding the refund.The 2nd time I do this purchase yesterday in the evening I receive confirmation email that I can collect the items at South Gate store.This morning I call 2 consultants who confirm that there is stock and my device is ready to be shipped then later on the day I receive an email that states there is no stock.I call the 3rd consultant n she states that there is stock at Centurion. How is it that only at the end of the day when supposed to receive item that’s when you are told it’s out of stock but there is confirmation that at Centurion there is stock.I will never buy anything online at Game.I want the device even now when you go online it states that there is stock available..I always buy online at Truworths n many other stores but I have never experienced this
