That is really disappointing if true.
Delta has come through for me in the past. In December, my wife was bumped off a first class leg due to the flight being cancelled, and the gate agent booked her follow-on flight in coach, without so much as a courtesy call. She took the flight because she needed to get to NC to drop off the gifts.
I called Delta afterwards and discussed it with the agent. They refunded me the mileage difference I'd paid for her fare base, and put another 20K miles in my wife's account as a way of apologizing.
I hope this story gets more airtime with Delta senior management, because they really should be taking care of folks that are caught up in this situation.
