No matter what they say even if you have to repeat yourself, and it has alwas worked for me, and I get the room for the price I was going to pay if not cheaper.
Something along the lines of:
"But sir, surely you cannot have lost my reservations, I have the confirmation in front of me that I will gladly fax to you immediately. Surely there is no way you lost my reservations at such a grand place as this. My confirmation is on front of me, I have the reservations. There is no way such a hotel as the Hilton lost my reservations. When I have booked my company here for conferences at other Hiltons they have never lost my reservations, so I cannot understand why it would happen now. I will be happy to wait and will be very patiant for you to clear this simple mistake up as I am sure that someone as important as you to this big hotel can get this done for me."
Good Luck.
EDIT: Repeat over and over, even if you sound like a confused old lady they will fix it. Ask them to get someone that does has authority and if they cannot offer that, then keep repeating yourself with kindness.
