It sounds to me like you are locked in a toxic and unending battle with your owners corporation, or at least your strata committee.
In your shoes I would seriously consider trying to undertake some kind of mediation in an effort to wipe the slate clean and start afresh. This is a war with no winners. Offering an olive branch is not waving a white flag. You and probably they have better things on which to expend time and energy.
I’m not talking about Fair Trading, but either a professional service that you can find on the internet, or our sponsors StrataAnswers.
It will cost a little but it could be a way forward.
