I don't disagree with that but I think it's premature to draw a conclusion. Unexpected events - even emergencies - can happen which are nobody's "fault" and don't afford an immediate opportunity for explanation.
I'm trying to imagine an explanation. I doubt the charter is out of business but decided to book the diver, charge his card, and hope he wouldn't notice or complain.
No it isn't, he booked a dive and received no call that it was canceled and he did everything he should have as the customer. Short of an alien abduction, being in jail or a tragic circumstance there is no excuse for him not to have received a notice--the day before--so he could re-book another operator--period. Enough of this fly by night stuff. Same thing with me in the Keys. N
