My guess is your letter got forwarded to the branch office, an overseer there saw it, had a heated conversation with the chairmen of your hearings, told them to get their act together and they're on their own if they screw up, and you got off the hook.
I appealed to the Society twice. EFG:ECH or whoever it was that wrote me back said they found no reason to question the judgments of the judicial committees, that's it, they didn't answer any of my direct questions.
A little off-topic, I love Joe Malik's story about how he wrote the Society a letter and later happened upon a certain GB member who poked him in the chest with his finger and said something like, "That letter of yours stirred up a lot of trouble!" lol
