False promise: delivery

I am so not impressed with Game's online shopping. On the 23rd November i made a purchase online and the email confirming my order said delivery will be done 3-5days. When i called on the 5th day was told due to black friday large volume of orders it would take up to 10 days. On the 29th November i received an email that my order has been dispatched from their warehouse. I still have not heard anything from the courier company and today is the 10th day. I called Game's customer service and was told to call Dawn Wing and arrange delivery with them. I have just been on the line with Dawn Wing now who told me they probably don't have the product with them yet as my reference doesn't exist on their system.

I bought a product with Game and delivery thereof should be liased between themselves and their courrier company. I have been wasting my airtime calling their custormer service centre and dawn wing with no assistance. Maybe the best thing to do at the moment would be to cancel the order seeing that no one knows where my order is.
