Query: Not happy with delivery (or non delivery) of this item

When I ordered this on 12/04/2006 they said I would have it before Christmas. Then right before Christmas the delivery date was changed to mid-January. So I had to cancel my order and go, at the last minute, buy it at a store because it was a Christmas present. I wasn't happy about it and won't be buying from amazon for the holidays any longer.
