Need information: Game Masters ignoring issue for a month. How to escalate issue?

I'd say just use Report a Bug
Say you can't level the two jobs because you don't have the job crystals and need an item restoration.

I think before asking for a restoration (and using up your one-time restore, particularly as it will only get one of the two), the simplest message might be "these key items were lost due to a rollback and cannot be reacquired within the game. Under normal circumstances they cannot be discarded so there is no in-game way to get them back. Can you fix this please?"

Lul.

SE doesn't pay enough people for job design/balance nor enough for in-game support/policing for how much they make.

Bet $$$ the GMs also do back end support as part of their job description considering how much work they don't do in-game.
