roxybody,
First thing I would do is check with your original shipper and see if DFI even recieved it, if not I'm sure you insured it and just put in a claim for it. If they did recieve it and you should have the e-mails showing the RNA # they gave you I'm sure they will help you out. I would put trace on your shipment and see if it was lost First. If they never recieved it there isn't really anything they can do to help you. I don't like how long or how much DFI charges for shipping...But they have always been very nice and heplful on the phone and though e-mails.
If it really is lost and you need one I know Detroitdr from this group is selling an almost new one, probably for less then the repairs and shipping costs would be anyhow. If you want look it is here.
