Poor service from Game stores

I displeased with the service that I have received from Game. On 2 occasions this past month I purchased stationery items for my kids and did they did not honor their 2-5 days delivery. Some of the items were out of stock and no notification came through, this does not reflect when you track the parcel either. The "solution" on both occasions was a refund, who covers the price difference from other retailers? Oh, and how is the length of the refund process helpful? These items are needed!!!! In my view you need to improve the way you treat your consumers, communicate better and do not advertise items that you do not intend selling so that you can stop consumers from purchasing from other retailers. Total waste of my time.
