I use my store's own local number if I need to get in touch via phone.
Try this number instead, i was contacted by them on it..
Office hours are the same as the above post..
This is a general number that goes through to a receptionist who will not be able to answer your queries!
Although GAME are inundated with customer service queries, but this really isn't the best way for you to go - you'll get more frustrated if they go via this route!
