This is a great move but be prepared that no one will care. Not CEDIA nor FORTRESS.

CEDIA cares about floor space revenue.
FORTRESS cares about sales revenue.

There are two types of sales people, those who want 'THE' sale, and those who want an ongoing relationship with YOUR business.

1) The sales guy who ratted you out is 'THE' sale guy and he's already picked his favorite dealer.

2) The manager who will hear the grievance is the same guy that hired him.
