Charlie99:I sounds like the instructor bit off more than he could handle --- with the current ripping and you and your buddy getting separated from the others, there is no way he could ride herd on 3 customers + you.
From what I read, the instructor said that all the divers were supposed to meet at the bottom of the mooring line, but the instructor wasn't there when the OP and his buddy arrived at the bottom. I wonder what set of circumstances caused the instructor to abandon that plan?
