IMO, you might have fared better if you were a bit more patient and asked permission or got clarification before jumping back into the game. You complained and then jumped right back in the game right away which is a sign that you are going to make trouble for the admin.
I'm sure the owner would side with the admin. If you want to end this situation well, I'd suggest just playing on the server, being a good citizen, and dropping it.
Or start your own server and have a hand at being an admin and see what a pain it can be for them.

(not that I have been an admin myself... I wouldn't want the hassle!)
