Pathetic service

I am trying to understand how a company as GAME can advertise an item on special and after ordering the item online to ensure I have reserved it and paid for it, for them to contact me 10 days later and tell me the item is sold out and they don't have stock. Surely this should have been indicated online BEFORE I placed the order and paid for the item. Why advertise something if you don't even have stock? Now I need to explain to a little boy why he can't have the Christmas present he asked for. It is pathetic service. If I could give you a ZERO rating, I would.
