What did you pay for your original ticket and what was the booking class and fare code? Did you have a OW or RT ticket (or multicity)? Can we assume that you purchased a coach ticket directly from DL? And did you sit in coach or FC on the new flight?
Exactly what did you say to the phone agent? Did you ask for a SDC (same day confirmed) or just ask for a change to your ticket, which normally would cost $200 plus the fare difference.
Note that coach tickets on DL require the same fare class availability for SDC, where you can (often) buy up to the higher fare class if your own fare class isn't available. A FC ticket should not require the fare class availability, only a (FC or coach if you're willing to downgrade) seat that DL is still selling on the flight. Also, nonelites pay a fee for SDC/SDS. If your ticket was rewritten into (almost full) Y class, you might have been given the last seat on the new flight.
