Hi sonle2001, in this case by cancelling first you may have limited your options. In the past when I had to make an emergency change to flight plans on an unrefundable ticket with a change fee, before cancelling anything I spoke with a Delta rep on the phone, who directed me to head to the airport with my medical docs. At the airport a rep made the schedule change for me (I had to stay at my current location for 2 weeks) with no fee upon review of my docs. As you've already canceled using the 'computer' which never makes exceptions, they may not be able to do as much for you.
