MNS – I edited your last post to avoid identifying who your strata managers are, but as neither their size or yours matters, my advice is is as before.
Contact Strata Community Australia NSW with your concerns and allow them to take up your case. If I’m any judge, I’ll bet that the Licensee of the Office that you’re dealing with doesn’t have the slightest clue about the difficulties that you’ve been experiencing with the individual Strata Manager concerned.
