Rebel Xsi Order

I've ordered a Rebel XSi 12mp SLR camera on Oct 12th 2009, the original shipping date for this item was on Nov. 2nd 2009. I've checked my estimate shipping date and it says N/A. and I still haven't received any other dates when the camera will be shipped. I am attending a wedding on the 22nd of November which is less than a week from now. Is there anyway I can make the order come any faster? Will the camera be shipped soon? What is causing the delay? Can someone please help me with this. Thanks.
