When we originally filled out the placement form we had to put down a primary and a secondary contact.
Who ever was the secondary contact for your camp could try contacting the placement team and letting them know that your Primary is unavailable.
Though, I'm the secondary contact for our camp, and I've gotten calls from Placement that only asked me to get ahold of our Primary and tell them to call BMorg. They wouldn't even really talk to me because I was the Secondary.
But, its worth a shot.
