GAME ONLINE SERVICE BEYOND POOR

I bought a Skyworth 43 inch TV online at game on the 29 April, the delivery turn around is written 2 - 5 days but still today the order is moved to the next business day. The courier wumdrop informed me on the 6th May that they don't find the order when they go to collect it for delivery, it isn't ready. The status on the order is 'handed to courier' I want a refund.
