Issues with cancellation and refund.

Based on the description of a stove on special I did an online purchase on 26 July. The next day I visited a Game store to view the item and the specifications were different to the ones listed on the site. I then cancelled the order and requested a refund, however the items still reflects as "Order confirmed" and out of stock. Following up my emails are ignored and speaking to a contact center agent multiple times all they mention is that the refund is sitting with head office and there is nothing further they can do.
