Non delivery of online order

Don't bother to order essential items from Game online. When I ordered it was stated that delivery will take 2-5 days. This was later changed to 5-7 days. My order had also not been delivered within the extended time. It is also of no use to query by e- mail as they do not bother to reply. Had I known that I can not rely on their delivery times I would not have bought on line. This is for sure first and last time I buy online from Game.
