Please give details as to what the "corroborating details" were on the page you subsequently faxed. What was the context and details of the discussion you had with the reservation agent hwereby you "subsequently faxed" the corroborating info.
Details may help the rest of us to figure out a pattern so that we can also get the VIP treatment.
Sometimes just being nice to the reservations agent (who has lots of discretion) will go a long way.
