The tip of the iceberg. Allegations include:
Jumpers who were promised that their bags would be taken in the non-jump plane DC-3s didn't receive then for another 3 days, so were stuck without any spare clothing etc, so incurred costs to buy clothes
Aircraft crews and jumpers arriving at Caen to find the promised accommodation and rental cars were non-existent and they were left to make (and pay for) their own arrangements
Photographers paying in advance for photo flights that never happened
Non-existent airshow at Caen (blamed on the weather, but allegedly the proper authorisations had not been obtained from the French)
People turning up at the event car parks and queuing for two hours for non-existent shuttle buses before giving up and going home
Promised trade stands and catering outlets not there, reports of only one burger van and nothing else
Aircraft parked tail-on a considerable distance from a metal fence was the nearest the public could get. The organisers then poured gasoline on the flames by posting close-up photos from liveside to show what a great event they were putting on
In short, a total shambles with a lot of people demanding refunds and threatening legal action
I'm glad we made a late decision on the day not to go to Caen and went elsewhere in Normandy instead.
