estimated delivery date

I've had the same problem i ordered mine 3/08 and they estimated my delivery date 3/18-3/23. Ok so first off that was unexpected but I guess 15 days isnt all that bad to wait. so the 18th came and nothing not even a shipping notification. "still in production". On the 21st I finally got an update stating "estimated delivery date 3/21 (updated)". So i assumed it was arriving that day the day passed and nothing. On the 23rd I called dells customer support and I was told it was expected the 23rd but had not been shipped yet. So unless the manufacturing facility was across the street I doubt this information was relevant. So its the 24th today and have not received my laptop and worst of all have not received any updated status. "estimated delivery date 3/21 (updated)" still appears when I search my order number, and It seems like such an insult. Dell is just saying "you'll get it eventually" which is fine and dandy but I have an Immediate use for it coming up. This is my first dell computer, and so far I am not impressed with the way they treat customers and how they process orders. I hope this doesn't keep up because I will probably just end up cancelling my order and going with a more trustworthy company.
