You didn't leave in a cloud of dust with a giant "F-you."
You approached the chief instructor to discuss a problem, and were summarily dismissed, and told you weren't welcome back.
I'm not impressed by the way he handled it. Not at all. There appears to be every reason to question whether he carried through on implied promises he made to you.
If or when you run into him again, it'll be easy to handle. Be polite and formal. Bow appropriately. Don't seek him out, don't chat with him.
Agreed.
This sounds like one of the "bow to the belt" situations. Sadly, there are too many of them around.
