No delivery of replacement item

I have been waiting for 4 weeks for a delivery on an item. Initial item was damaged upon delivery. It took game 4 weeks to collect the damaged item and now four weeks later I still wait on the delivery of my item which was paid for in July already. No way of escalating the matter and they do not resolve the matter. Only get passed on every time we phone. This is very bad customer service and I would not recommend Game for online shopping. Who can I contact to resolve my order
